Best arch support insoles and night splint for plantar fasciitis: a detailed guide

Who is this guide for, and why should you read it?

Sharp, stabbing pain under the heel when you get out of bed. An ache across the arch that builds during a long shift on hard floors. A pull under the foot that starts to limit your running or training.

If that sounds familiar, this guide is likely to be relevant to you.

Plantar fasciitis is a very common cause of heel pain in adults. It often affects people who spend many hours on their feet at work, and it is very common in runners and active adults. For some people it settles over a short period; for others it becomes a longer‑term problem that interferes with walking, work, and sport. It can be particularly frustrating when the pain seems to ease for a while. As soon as you try to get back to normal activity, it flares again. Most cases improve with the right combination of self‑care and, where needed, clinical support. Here, “self‑care” mainly means changing how the foot is loaded – time on your feet, surfaces, supports, and exercises – rather than only resting.

In this guide we’ll look at:

• What the plantar fascia is and what plantar fasciitis actually means.
• Why pain behaves the way it does – the sharp morning steps, the ache that builds with time on your feet, and what changes when you walk or run differently.
• How our FootReviver™ Orthotic Plantar Fasciitis Insoles and our plantar fasciitis night splint have been designed, with input from podiatrists and physiotherapists, to change how your heel and arch are loaded.
• How to use them sensibly alongside changes in activity, simple exercises, and any advice from your GP, physiotherapist, or podiatrist.

The aim is to give you clear, practical guidance about how these supports fit into managing plantar fasciitis, so you can see whether they belong in your own plan to calm your heel pain and stay as active as you reasonably can.

What is the plantar fascia, and what does it do?

The plantar fascia is a strong band of tissue that runs along the bottom of your foot from the underside of the heel bone towards the toes. It fans forwards along the arch and then splits towards the bases of the toes. It is a dense, tendon‑like band rather than a muscle, so it tolerates tension but does not actively contract.

It helps to:

• Support the arch, acting like a tensioned strap.
• Share load between the bones and joints when you stand, walk, or run.
• Stiffen the foot slightly as you push off, so each step or stride is more efficient.

Most of the time it does this quietly in the background. Problems start when the area where it attaches to the underside of the heel bone becomes irritated.

What is plantar fasciitis in simple terms?

Plantar fasciitis means irritation of the plantar fascia, usually where it joins into the heel bone on the inner underside of the heel.

Rather than a single tear, it is usually a build‑up of small stretches and pulls at that attachment point. Over time, these repeated small strains can outpace the tissue’s ability to repair itself, leading to local irritation and some thickening of the fascia. The collagen fibres in the fascia can also become more disorganised, which makes it less efficient at sharing load. That patch of tissue becomes very sensitive to normal pulling and pressure. The nerves in that region also become more reactive, so forces that used to feel normal now cause sharp or aching pain.

How much strain the fascia is placed under depends on:

• How you stand, walk, and run.
• How much time you spend on your feet.
• Your footwear.
• Your foot shape and ankle movement.
• Changes in bodyweight and activity.

How does heel and arch pain from plantar fasciitis usually behave day to day?

Day to day, heel and arch pain of the type seen in plantar fasciitis tends to become noticeable at particular moments. Many people describe three main features.

First, there is the sharp, stabbing pain under the heel on the first few steps out of bed, or after you have been sitting for a while. Then, as the foot “warms up”, the pain may ease a little. As the day goes on, especially if you are on hard floors, an ache can build across the heel and along the inside of the arch. And if you run or do impact exercise, you may notice a pulling or bruised feeling under the heel or arch as you push off, with pain that often feels worse later that day or the following morning.

If this type of pain continues for many weeks or months without changes in how the foot is loaded, the tissue can stay irritated and pain can become a longer‑term, chronic problem.

These symptoms are familiar for many adults, especially runners and people who stand a lot. For some, the pain settles with a short spell of rest and simple stretches. For others, it becomes a daily problem that affects walking, work, and training. Later in this guide we look at what is happening inside the plantar fascia that creates this timing – especially why those first steps after rest can feel so much worse.

Our FootReviver™ Orthotic Plantar Fasciitis Insoles and our plantar fasciitis night splint have been shaped with these symptoms in mind, using feedback from podiatrists and physiotherapists who see plantar heel pain regularly.

What kinds of supports can help plantar fasciitis?

If you recognise this type of heel or arch pain, you have probably come across ideas such as “arch support insoles” or “night splints”. It helps to be clear what these are before going into the detail of how they work and why they might suit you.

What is an arch support insole for plantar fasciitis?

An arch‑support insole is a shaped insert that sits inside your shoe, under your foot. When you stand or walk on it, the shape influences how your heel and arch take your weight. A plantar fasciitis‑focused design, like our FootReviver™ insoles, usually includes:

• A firmer, contoured area under the inner heel and arch to guide how your foot sits and moves.
• A shaped heel cup to keep the heel sitting steadily over that support and to help hold the natural fat pad under the heel bone.
• A cushioned top layer so standing, walking, and easier running feel more comfortable.

Our FootReviver™ Orthotic Plantar Fasciitis Insoles are shaped with clinical input to support the plantar fascia at the heel and along the arch, rather than simply adding a flat layer of padding.

The idea is to change how your heel and arch take your bodyweight each time you stand, walk, or run, rather than just adding softness under the whole foot.

What is a plantar fasciitis night splint?

A plantar fasciitis night splint is a brace you wear while you sleep. It holds your foot at roughly a right angle to your shin instead of letting it hang down. Our splint uses:

• A structured bar to maintain that angle through the night.
• Broad straps to hold your foot and lower leg in place.
• Gentle compression to keep the fit snug without digging in.

Its job is to stop the plantar fascia and calf tightening right up overnight and to soften the sudden stretch and pressure when you first stand up. This is aimed at the same sharp first‑step pain described earlier. Later on this page we will look at exactly how our splint is designed to target that problem, and how the night splint and insoles work together.

Could my heel pain be something other than plantar fasciitis?

Heel pain has several possible causes. Plantar fasciitis is common, but it is not the only explanation. A clear diagnosis usually needs assessment by a clinician, but recognising some symptoms can help you judge when self‑care and supports are sensible, and when you should be assessed first.

When clinicians say heel and arch pain is “suggestive of plantar fasciitis”, they usually mean heel and arch pain that behaves like this:

• Pain is felt mainly under the heel, slightly towards the inner side, sometimes spreading a short way into the arch.
• It is at its worst on the first few steps after getting up, or after sitting, then eases a little as you move.
• It often returns as a dull ache after longer spells of standing or walking, especially on hard floors, and may flare after heavier activity such as a long walk or run.

This is different from pain at the very back of the heel, which is more typical of Achilles tendon problems; from pain with numbness or tingling into the toes, which is more in keeping with nerve irritation; and from pain that starts suddenly after a fall or twist with marked swelling, which can suggest a bone or joint injury. Pain at the back of the heel usually reflects irritation of the Achilles tendon where it joins the heel bone, rather than the plantar fascia under the heel. Nerve‑type pain can arise from irritation of small branches of the main nerve to the sole, for example where they pass behind the inner ankle or through tight spaces in the foot. A stress fracture is a small crack or area of stress in the bone itself, which behaves differently from soft‑tissue irritation like plantar fasciitis. Redness, warmth, and significant swelling around the heel, particularly if you feel unwell, can point towards infection or an inflammatory condition. Widespread joint pain, early‑morning stiffness in several joints, or symptoms in both feet together may link to inflammatory arthritis.

These symptoms do not automatically rule plantar fasciitis in or out, but they are all strong reasons to get things checked rather than assuming it is straightforward plantar fasciitis. If any of these other symptoms sound familiar, it is especially important to be assessed rather than assuming plantar fasciitis.

How do heel spurs fit into this kind of heel pain?

A heel spur is a small bony growth that can form where the plantar fascia attaches into the heel bone. If this attachment area is stressed over a long period, the body may lay down extra bone there. This extra bone forms gradually at the site where the soft tissue repeatedly tugs on the bone. Spurs often form gradually and may be present long before any pain starts. Some people have heel spurs and no pain at all, while others have typical plantar‑fasciitis‑type heel pain but no spur on X‑ray.

Whether or not there is a spur, the main mechanics are similar. Repeated pulling of the plantar fascia at its heel attachment can irritate the soft tissues and their junction with the bone. The body sometimes responds by building extra bone at that spot, which appears as a spur on X‑ray. The nearby soft tissues stay sensitive, so impact and stretch still hurt. In practice, the discomfort is more about the irritated soft tissue and its junction with the bone than the spur itself. In day‑to‑day life, heel spur–related pain often feels very similar to the heel pain described earlier because it affects the same inner underside of the heel. This is why treatment often focuses more on how the heel is loaded than on the spur itself.

Our FootReviver™ insoles and night splint are still relevant in this situation. By supporting the arch, helping the heel sit steadily, and reducing sudden first‑step pulls, they aim to reduce irritation at the fascia attachment, whether or not a spur is present.

When should I speak to a clinician before relying on supports?

It is sensible to speak to a GP, physiotherapist, or podiatrist before relying on insoles or a night splint if:

• Heel pain is severe, sudden, or linked to a clear injury or a sharp change in training.
• There is significant swelling, redness, warmth, or skin change around the heel.
• You notice loss of feeling, marked weakness, or changes in foot colour or temperature.
• Pain is rapidly worsening, spreading, or not improving at all over several weeks despite rest and basic self‑care.
• You have a history of circulation problems, diabetes with nerve changes in the feet, or inflammatory arthritis.

For many adults with a gradual build‑up of this type of heel pain, including runners who can link symptoms to a training increase rather than a one‑off incident, self‑management using supports and exercise is reasonable. It just should not replace a proper assessment if any of the worrying signs above are present.

What is going on in the plantar fascia itself?

The plantar fascia runs along the sole and anchors into the heel. In plantar fasciitis, you usually see repeated small stretches and pulls where it meets the heel bone. The local tissue can become irritated and, in some people, thickened, and the collagen fibres can become more disorganised. The nerves in the area become more sensitive, so forces that used to feel normal now cause sharp or aching pain.

Each time the arch drops further than the fascia can comfortably manage, that attachment is tugged. Your body tries to reinforce that area by laying down extra tissue, but that tissue is often less stretchy. Over time, the fascia and the structures around it become less willing to tolerate normal loads.

Overnight, when you are asleep, your feet often fall into a pointed‑down position. In that posture the plantar fascia and the calf–Achilles complex shorten, and the irritated tissue at the heel sits in a shortened position for hours. When you then stand up and your ankle and toes move up, that shortened, sensitive tissue is suddenly stretched and pressed against the heel bone. That is the main reason those first bare‑foot steps after rest can feel so sharp. For many people, understanding this is an “aha” moment that makes sense of why mornings can be so difficult even though they have been resting.

The plantar fascia becomes less tolerant of strain at its heel attachment, so everyday loads that once felt normal can now feel like too much. This is the background problem that the rest of your symptoms – and the treatment options discussed here – are built on.

How do my foot, leg, and gait affect plantar fascia load?

Now that we have looked at what the plantar fascia is and how it becomes irritated at the heel, it helps to see how your walking and running style can add to that strain.

In a reasonably well‑balanced foot during walking, the heel touches the ground first. The foot rolls slightly inwards (a small amount of pronation, which is normal) to absorb shock and spread load, and the plantar fascia starts to tighten as the arch accepts weight. As your body moves over the middle of the foot, the arch lowers a little but does not fully collapse. The fascia supports the arch and shares load with muscles and ligaments. As you push off, weight moves towards the ball of the foot and toes, the big toe bends upwards, and the fascia tightens further, helping to stiffen the foot into an effective lever.

The plantar fascia is put under extra pressure when this normal sequence is exaggerated or poorly controlled. If the foot rolls inwards excessively (over‑pronation), the heel may tilt inwards and the arch can drop more than it can comfortably manage. The plantar fascia is then stretched again and again at the inner heel. If the arch is very high and the foot is quite rigid, it does not lower much at all. The foot absorbs less shock, so more of the force from each landing goes straight into the heel and fascia. If the ankle is stiff and the calf tight, the ankle may not move up easily as you move over the foot. Your body may then roll the foot in more or lift the heel early to keep you moving, both of which change how force passes through the fascia and can increase strain.

The foot does not work in isolation. If your knees tend to drift inwards when you stand, walk, or run, the thigh and shin bones turn inwards, which usually encourages the feet to roll inwards more, adding load to the inner heel and arch. This often reflects reduced control from the muscles around the hips, particularly the muscles at the side of the hip (gluteal muscles) that normally help keep the knee lined up over the foot. If these muscles are not working strongly enough, the thigh can roll inwards further with each step, which again adds strain to the inner side of the foot.

When you run, the same principles apply but the forces are higher and there is less time for the foot to share load. Your foot spends less time on the ground with each step, but the force on each contact is higher. The arch and plantar fascia have to absorb and then release that force quickly for every stride. This is why the same underlying mechanics can feel much more intense when you run than when you walk. If training volume or intensity climbs more quickly than these tissues can adapt (strengthen and repair themselves between sessions), irritation at the heel attachment can build, especially if the foot is flattening heavily or the calf and ankle are stiff.

Are there gait changes that might ease strain on my plantar fascia?

Some small adjustments to how you walk or run can reduce the stress on the plantar fascia, especially when combined with insoles and strengthening. For walking, taking slightly shorter, quicker steps rather than long, heavy strides can reduce the impact on the heel and the amount the arch has to drop with each contact. Trying to keep your knee broadly over the middle of your foot, rather than letting it drift inwards, can also reduce inward roll at the ankle.

For running, it is usually not wise to overhaul your technique overnight. However, being aware of very long over‑striding – landing with the foot far in front of the body – and very heavy heel strikes on steep downhills can be useful. Some people benefit from gently shortening their stride and allowing a slightly quicker, lighter step pattern, particularly when running downhill. Any change should be gradual, and ideally discussed with a clinician or coach if you are unsure.

Which activities and changes often trigger or worsen plantar fasciitis?

Plantar fasciitis often follows changes in how much stress the heel and arch are asked to handle, rather than one single incident.

You might notice that pain started or flared when you sharply increased how far or how often you walked or ran. For example, you may have gone from gentle, short walks to long, fast walks most days, or from occasional easy runs to more frequent runs at a higher pace. Spending a lot more time on hard floors can also be a trigger. Hours of standing in one place or walking on firm, unpadded surfaces, with little chance to sit or change footwear, add many similar loading cycles to the fascia.

In runners, a sudden increase in running up and down hills or slopes is a common factor. Running faster than you usually do means your foot spends less time on the ground with each step and each landing puts more force through your heel and arch. Running uphill makes you push off more strongly through the forefoot, asking more of the calf and plantar fascia. Running downhill often means your heel hits the ground more firmly to slow you down, sending more force into the sore area under the heel. If these changes are brought in quickly, the plantar fascia can be asked to cope with more force than it is ready for.

Changes in bodyweight also matter. Higher bodyweight means more force through the foot with every step. Over weeks and months, that extra force can add up and irritate the fascia. It is one factor among many, and weight management, where appropriate, is usually only one part of a wider plan. Returning to full activity too quickly after a previous spell of heel pain is another common story. If the fascia has not had enough time or small, step‑by‑step increases in activity to rebuild its strength, going straight back to previous walking or running demands can upset it again.

Recognising these kinds of changes can help you plan more gradual, sustainable adjustments in walking, standing, and running. Looking back at changes in distance, speed, hills, or time on your feet can help you plan more gradual, sustainable adjustments. If this sort of increase in demand continues without adjustment, it often feeds into the ongoing cycle of irritation described next.

Why does plantar fasciitis sometimes keep coming back or not seem to settle?

Many people notice that heel pain eases with rest, then flares again when they try to get back to normal walking or running. Rather than a single injury, this usually reflects an ongoing cycle.

A typical sequence is that you go through a period of increased walking, standing, or running, and the plantar fascia becomes irritated at the heel. Morning pain and post‑activity ache appear. To protect the area, you change the way you move. You may limp or avoid putting weight squarely on the heel, shifting load elsewhere in the foot and leg. The plantar fascia and nearby tissues stiffen and become more sensitive. The nerves in that region become more reactive (sometimes described as “sensitised”), so even usual forces feel painful. Overnight, the band shortens in a protected position.

When you stand up, that shortened, sensitive tissue is suddenly pulled and pressed, giving sharp pain on the first steps. Because walking and standing hurt, you may cut down your activity. Muscles around the ankle, knee, and hip lose some strength and endurance, giving the arch and heel even less support. Each time you try to increase your walking or start running again, the fascia has not yet regained what it can comfortably handle, so even modest increases in load can cause another flare.

Many people recognise this as the point where they simply feel stuck with their heel pain. Understanding this cycle often helps explain why the problem seems to come back each time you try to be more active. Breaking it usually means doing two things together:

• Changing how and how much the fascia is being loaded, so it is not irritated in the same way day after day.
• Gradually rebuilding the capacity of the fascia and the supporting muscles with time, movement, and strengthening.

Insoles and a night splint mainly help with the load‑change part by altering how and when the fascia is stressed during the day and overnight.

How do I know if a pain flare means I have done too much?

Some increase in symptoms when you start moving more again is common, and not every rise in pain means you have damaged the fascia further. As a rough guide, many clinicians use the next 24–48 hours of symptoms to judge whether an activity level was tolerable.

A mild, short‑lived increase in discomfort that settles back towards your usual level within about 24 hours can be acceptable. For example, a slightly sore heel the evening after a longer walk that feels back to baseline by the following morning may just be your tissues adapting.

By contrast, a flare that is clearly stronger than usual and lasts more than 24–48 hours, especially if morning first‑step pain is noticeably worse, suggests you have asked for more than the fascia can comfortably handle at this stage. In that case, it is sensible to reduce the volume or intensity of what you are doing, or to change one element such as distance, hills, or speed, rather than pushing on. You can use next‑morning first‑step pain and end‑of‑day ache as guides to adjust your plan, including when building up walking and running as outlined later.

Using this simple approach – watching how symptoms behave over the next day or two – can help you adjust activity without guessing.

What else, besides insoles and a night splint, usually helps plantar fasciitis?

Many people do best with a combination of measures, not just one change. Alongside insoles and a night splint, commonly used options include:

• Gentle stretching for the calves and the sole of the foot.
• Gradually building strength in the muscles of the foot and calf.
• Thoughtful changes to how much time they spend on their feet or running, especially after a flare‑up.

These measures aim to improve flexibility and strength so the foot can cope better with the forces described earlier, and to change how often and how strongly the fascia is being stressed. A physiotherapist or podiatrist can help you put these pieces together into a plan that fits your life.

What simple stretches can help take pressure off my plantar fascia?

Gentle stretching can help reduce tightness in the calf and under the foot, which in turn may lessen the pull on the plantar fascia at the heel. Two commonly used stretches are:

• A straight‑knee calf stretch: stand facing a wall, place your hands on the wall, step the sore side back with the knee straight and heel on the ground, and gently lean forwards until you feel a stretch in the upper calf.
• A bent‑knee calf stretch: from a similar position, bend the back knee slightly while keeping the heel down, to target the lower calf and Achilles area.

You can also gently stretch the sole of the foot by sitting, crossing the affected leg over the other, and using your hand or a towel around the forefoot to gently draw the toes up towards you until you feel a mild stretch under the arch. This targets the band of tissue under the arch (the plantar fascia) and the small muscles in the sole of the foot. Stretches should feel like a gentle pull, not a sharp pain, and are often held for 20–30 seconds and repeated a few times a day. If a stretch consistently causes sharp pain rather than a mild pull, it is sensible to ease off and seek advice rather than forcing through it.

What strengthening exercises are often used alongside supports?

Strengthening the muscles that support the arch and control the ankle can help share load with the plantar fascia. Simple options include:

• Foot intrinsic exercises, such as gently shortening the arch (“short foot” exercise) by drawing the ball of the foot towards the heel without curling the toes, or using a towel on the floor and slowly pulling it towards you with your toes. These are aimed at strengthening the small muscles that help support the arch from within the foot.
• Calf raises, starting with both feet on the floor, rising up onto the balls of your feet and lowering in a controlled way. Over time, and with guidance if needed, this can progress to single‑leg raises and then to doing them on a small step so the heel can drop slightly below the step at the bottom of the movement. If you also have Achilles tendon symptoms, it is wise to introduce step‑based calf raises cautiously and, if possible, with guidance from a clinician.

These exercises should be introduced gradually and adjusted if they cause a clear, lasting flare in symptoms. By improving flexibility and strength, they help the foot cope better with the forces described earlier, making each step less provocative. Over time, stronger calf and foot muscles can help the plantar fascia by sharing more of the work with each step. Our insoles and splint are intended to sit alongside this kind of strengthening, not to replace it.

How should I change my walking or standing habits to help my heel?

Long periods of standing still on hard floors can be particularly difficult for plantar fasciitis. If your work or daily life involves this kind of standing, taking brief sitting breaks where possible, changing position regularly, and using footwear with some cushioning and support can help. When you do have control over surfaces, choosing slightly softer ground rather than very hard pavements, especially in the early stages of a flare, can also be useful. Gentle movement means the load shifts slightly with each step and blood flow is better, whereas standing still keeps constant pressure on the same part of the heel. Many people find that steady, moderate‑paced walking is better tolerated than very long static standing. Even small changes in how long you stand in one place, or which surfaces you stand on, can make a noticeable difference to how irritated the heel feels by the end of the day.

Alongside these exercise and habit changes, many people benefit from supports that directly change how the heel and arch are loaded, such as insoles and a night splint, which we turn to next.

How a plantar fasciitis night splint works on your foot and heel

A plantar fasciitis night splint is aimed at the part of the day when you are not moving. It aims to change what happens to the fascia and calf while you sleep.

Earlier we saw that when you sleep, your feet often fall into a pointed‑down position. In that posture the plantar fascia and calf–Achilles complex shorten, and the irritated tissue at the heel sits in a shortened position for hours. When you then stand, your ankle and toes move up, suddenly stretching and loading that sensitive area, which is why those first bare‑foot steps can feel so sharp.

Our FootReviver™ plantar fasciitis night splint is designed to hold the foot close to a right angle to the shin, which keeps the fascia and calf gently stretched overnight and reduces how much they can shorten. When you stand, the change in position is smaller, so there is less of a sudden pull on the sore area at the heel. The aim is not to pull hard, but to keep things just stretched enough that the first few steps in the morning are less of a shock.

In our splint, the straps hold your foot and lower leg securely so the set angle does not sag as you relax. You can adjust how much the foot is held up so you can find a stretch that you feel but can tolerate through the night. The snug fit gives gentle, even pressure around the foot and calf. A metal bar running along the front or back keeps the splint’s shape so your foot is consistently held in that angle, not just for the first few minutes. It should feel secure but not tight to the point of pins and needles, numbness, or cold toes.

Because our night splint holds the ankle in a set position and applies a gentle stretch, it may also be used, with specific professional advice, in some people with Achilles tendon irritation near the heel, where night‑time shortening can also lead to painful, stiff first steps, and in certain heel spur patterns where the plantar fascia attachment is involved. If you have poor circulation, nerve problems, or fragile skin on the lower leg or foot, you should check with a clinician before using a splint like this, as reduced sensation or blood flow can make it harder to notice pressure or tightness developing.

How should I build up time in the night splint?

When fitting our night splint, put it on while sitting, with your foot at about a right angle to your shin. Tighten the straps so it feels secure but not constricting. You should feel a gentle stretch at the back of the leg or under the foot, not a strong pull. As a rough guide, a moderate stretch that you can fall asleep with is more useful than a strong pull that keeps waking you.

To begin with, you might wear it for an hour or two in the evening while you are resting and then take it off for sleep. As you get used to it, you can wear it through part of the night and, if comfortable, build up to most of the night. A mild ache in the calf or under the foot as tissues adapt can be quite common. If you feel tingling, numbness, strong pain, or notice changes in colour or temperature of the foot, you should remove it and seek advice. You should not walk around in a rigid night splint. If you need to stand briefly, take care and follow any instructions that come with the product.

Everyone is a little different, but many people find that first bare‑foot steps are a little less severe after several weeks of wearing a night splint most nights. If the problem has been going on for many months, improvements are often gradual and take time.

What if I find it hard to sleep in a night splint?

It is common to find a night splint unfamiliar, and sometimes a little awkward, at first. Our night splint is padded and made from soft, breathable materials to reduce pressure points and heat build‑up, but any structured support can still feel strange when you first start wearing it. It often takes a few nights of trial and adjustment to find a position that feels comfortable enough to sleep in.

If you are struggling to sleep in it, it can help to reduce the amount of stretch slightly by adjusting the angle so the foot is closer to neutral, and to build up time gradually rather than trying to wear it all night straight away. The aim is a gentle stretch that you can mostly ignore in the background, not a strong pull that keeps you awake.

For example, you might wear the splint for part of the evening while you are sitting, and then for a few hours at the start of the night before removing it. This allows your body to get used to the sensation in stages. A thin sock under the straps can help protect sensitive skin and reduce any rubbing.

If, despite adjusting the angle and building up gradually, you find it very difficult to tolerate, it is worth discussing this with a clinician, as they can advise whether to modify, continue, or stop using the splint in your particular situation.

Should I use the night splint on both feet if only one heel is sore?

If only one heel is affected, many people choose to splint just that side. In situations where both heels have similar symptoms, or where calf tightness is a major issue on both sides, a clinician may sometimes suggest using splints on both feet. Whatever you choose, it is important to make sure the splint is not causing pressure areas, numbness, or circulation problems on either side.

When does it make sense to use both insoles and a night splint together?

For many people, especially those with severe morning pain and long days on their feet, using both supports can be more helpful than using either alone.

Our FootReviver™ insoles are aimed at making each step feel less uncomfortable on the heel and arch by controlling arch drop, supporting the heel, and sharing pressure under the foot. They mainly address the load‑during‑the‑day part of the plantar fasciitis cycle. Our FootReviver™ night splint is aimed at stopping the fascia tightening right up overnight and at softening the first‑step stretch. It mainly targets the painful‑mornings part of the cycle.

You may find both particularly helpful if you spend long days on hard floors and find that your heel pain grows through the day and then flares sharply again after rest, or if you dread your first bare‑foot steps in the morning or after a long car journey because of the sudden pain. People who have a mix of everyday standing and walking plus some running or sport often want the fascia to be better supported both during activity and at rest. In that case, insoles can go into work and training shoes, while the splint works overnight.

Because the FootReviver™ insoles and FootReviver™ night splint were developed to work together in this way, they offer a coordinated approach: one acting mainly on daytime standing and walking, the other on night‑time shortening and first‑step pain.

Our products are intended as supports rather than cures. Plantar fasciitis is usually influenced by several factors, so no single measure is likely to be a complete solution on its own. They are there to make sensible changes easier to manage, not to replace them.

How can I safely build my walking back up once pain starts to ease?

The same simple “watch what happens over the next 24–48 hours” approach described earlier can guide how you build your walking back up.

Once your symptoms begin to settle, many people want to regain lost walking fitness but are understandably cautious about provoking another flare. A gradual approach is usually best. You might start with shorter walks on flatter, slightly softer surfaces, such as parks or paths, rather than very hard pavements. Keeping a rough idea of how long you are walking for and increasing that time by small amounts – for example 10–15% per week – can help you progress without jumping too quickly.

Paying attention to your heel in the 24–48 hours after a walk is important. If your first‑step pain the next morning and end‑of‑day ache feel similar to or slightly better than usual, you are probably at a manageable level. If they are clearly worse and stay that way, it is a sign to reduce either the distance, the speed, or the surface hardness for a while before trying to progress again.

How can I phase back into running if I have taken a break for plantar fasciitis?

Returning to running after plantar fasciitis needs a bit more planning than simply picking up where you left off. Many people do well with a walk–run approach at first, using short periods of gentle running separated by walking breaks. You might, for example, alternate one or two minutes of easy running with one or two minutes of walking, keeping the total time of the session modest. This keeps each run segment shorter to begin with, which usually makes it easier for a sensitive heel to cope.

Early sessions are usually best kept on flatter routes with fewer hills, and at a gentle pace that feels easy to control, rather than at a speed where you are pushing hard or landing heavily with each step. It is often helpful to change only one variable at a time: distance, speed, or hills. Increasing distance first, then very gradually adding some hills, and leaving faster running or sprint‑type work until last is a common pattern.

Our FootReviver™ insoles can be used in many running shoes and may make easier runs and everyday walking less uncomfortable while the fascia regains tolerance. The night splint can help with morning stiffness during this phase. They do not, however, remove the need to listen to your symptoms and to progress training steadily.

Are these plantar fasciitis products suitable for me, and when should I get more help?

Our FootReviver™ Orthotic Plantar Fasciitis Insoles and our FootReviver™ plantar fasciitis night splint are designed for adults with heel and arch pain of the type seen in plantar fasciitis. They are one part of looking after the problem yourself and do not replace medical care where that is needed.

They are usually most helpful if you:

• Have gradual‑onset pain under the heel or along the arch that matches the features described earlier.
• Walk, stand, or run regularly and would like to reduce the stress on your plantar fascia during those tasks.
• Can wear closed‑back shoes that have enough room to take a structured insole.
• Are prepared to bring the products in gradually and to combine them with changes in activity and exercise.

You should be cautious or seek advice before use if you have known circulation problems in your legs or feet, diabetes with reduced feeling in your feet, or another condition that affects sensation, open wounds, ulcers, or fragile skin on the areas that would press against the insole or splint, have recently had surgery to the foot, ankle, or lower leg, or suspect a bone injury such as a stress fracture or a tendon tear, especially if there is sudden pain, swelling, and difficulty bearing weight.

Stop using the products and get professional advice if pain suddenly becomes much worse, particularly after a twist, fall, or heavy impact; if you notice new or increasing swelling, redness, or warmth in the heel or foot; if you develop numbness, tingling, or clear colour changes in the toes or foot; if symptoms spread quickly or you feel unwell at the same time as worsening foot pain; or if there is no improvement at all after several weeks of regular use, or your ability to walk, work, or run is steadily getting worse. The main warning signs to look out for are the same as those listed earlier in the “when to see a clinician” section.

How long does plantar fasciitis usually take to improve?

Recovery time varies from person to person. For some people, especially if symptoms have only been present for a few weeks and changes are made early, heel pain can ease significantly over a few months with sensible load management, exercises, and support.

If pain has been present for several months or longer, improvement is still possible, but it tends to be more gradual. It is common for symptoms to fluctuate from day to day and week to week, with slow overall progress rather than an overnight change. Many people notice that, over time, morning pain becomes less sharp, walking on hard floors feels more manageable, and they can steadily increase activity again. The longer the fascia has been irritated, the more time it usually needs to settle and rebuild its tolerance, so patience and consistency tend to matter more than any single “quick fix”. Looking at progress over several weeks, rather than day by day, is often a more realistic way to judge how things are changing.

If there is no clear improvement at all after a few months of regular self‑care and support, or your ability to walk and work is getting worse, it is important to seek further assessment to check that nothing else is going on and to review your plan.

Common myths about plantar fasciitis and insoles

A few misunderstandings often come up when people talk about plantar fasciitis:

• “If I can still walk, it can’t be plantar fasciitis.”
  Many people with plantar fasciitis can walk, but have a particular type of heel pain that is worse with first steps after rest and after longer periods on their feet.
• “Rest alone will cure it.”
  Rest may calm symptoms for a while, but without changing how the heel and arch are loaded and gradually rebuilding strength and tolerance, the same pain often returns when activity increases again. Prolonged rest can also leave the fascia and the muscles around the foot and ankle less conditioned, so when you start doing more again the area may feel even more sensitive.
• “Insoles will make my feet weak.”
  Well‑designed insoles are intended to reduce excessive strain and allow you to stay active. When pain is lower, you are usually able to walk and exercise more, which keeps muscles working. By allowing you to keep walking and exercising with less pain, they can actually help you maintain or improve strength, rather than losing it through inactivity. Insoles should sit alongside, not instead of, strengthening.
• “I should push through as long as I can tolerate the pain.”
  Persisting with unmodified activity that keeps provoking the same pain response can keep the cycle going. As explained earlier, simply repeating the same loads that irritated the fascia in the first place usually means the problem continues. Adjusting volume and intensity, and using supports to reduce strain, is usually more effective than simply enduring symptoms.

What are sensible next steps if I think I have plantar fasciitis and want to manage it properly?

If your heel and arch pain matches the features described for plantar fasciitis, it helps to recognise that the plantar fascia is being irritated by how it is loaded at the heel and arch, particularly with repeated inward rolling, firm heel strikes, and overnight tightening. Long‑standing pain usually reflects a cycle of overload, guarded movement, stiffness, and reduced activity, rather than a single event.

Because plantar fasciitis is driven by how the fascia is stressed at the heel and arch, the most effective strategies usually combine changes in loading with supports that directly modify those stresses. Supports that directly change the way forces go through your heel and arch, such as our FootReviver™ Orthotic Plantar Fasciitis Insoles during the day and our FootReviver™ plantar fasciitis night splint at night, can sit alongside stretching and strengthening exercises, changes in time on your feet, and attention to footwear, training patterns, and surfaces. The insoles are designed to steady the heel, limit excessive arch drop, and share pressure under the foot, while the night splint aims to reduce overnight tightening and the shock of first bare‑foot steps.

Because they act on the specific mechanical issues that drive this type of heel pain, supports like these often make it easier to put the rest of your plan into practice. If this sounds like your heel pain, our FootReviver™ insoles and night splint are designed to address the specific loading problems described here, and are a reasonable option to consider alongside advice from your GP, physiotherapist, or podiatrist. If you are unsure about the cause of your pain, notice any of the warning signs listed above, or are not improving, it is important to speak to a clinician, especially if you are a runner or athlete and want to return to or maintain your sport safely. If you are unsure how these supports might fit into your own situation, discussing them with a GP, physiotherapist, or podiatrist can help you decide.

When plantar fasciitis is managed in this way, many people are able to bring this type of heel pain under much better control and return to the activities that matter to them.

Important information and disclaimer

The information on this page is general guidance about heel and arch pain of the type seen in plantar fasciitis. It is not a personal medical consultation and does not replace advice, diagnosis, or treatment from a GP, physiotherapist, podiatrist, or other qualified professional.

Our FootReviver™ Orthotic Plantar Fasciitis Insoles and our FootReviver™ plantar fasciitis night splint are intended for adult use. They are designed to reduce strain on the plantar fascia and make walking, standing, or light running more manageable, but no specific result or cure can be guaranteed.

You should seek individual advice if your symptoms are severe, changing quickly, or not improving despite steady self‑care; if you have underlying medical conditions such as diabetes, circulation problems, or nerve disorders; or before using these products for any purpose other than plantar‑type heel and arch pain. Only a clinician who has assessed you can confirm your diagnosis and advise on the most appropriate treatment and safe use of any supports or splints.
