Shock absorbing insoles for Trainers & Running shoes

Plantar Fasciitis

Plantar fasciitis is inflammation of the plantar fascia—a thick band of tissue that runs along the bottom of your foot from your heel to your toes. It’s a common condition affecting many people at some point in their lives. Runners are particularly susceptible because of the repetitive heel strike and the cumulative load on the plantar fascia.

The plantar fascia acts like a bowstring, stretching and absorbing some of the impact with every heel strike. But if the impact is too great, or if it’s repeated too often without adequate recovery, the fascia develops micro-tears—tiny damage to individual fibres—near where it attaches to your heel bone. The attachment point takes the highest tension because that’s where all the pulling force concentrates when the fascia stretches. This leads to inflammation and pain.

You’ll typically feel sharp, stabbing pain in the heel, especially with the first few steps in the morning. The pain often improves after a few minutes of walking but returns after long periods of standing or after getting up from sitting. It’s worse after long runs, especially on hard surfaces like concrete or tarmac. It tends to worsen after exercise rather than during it.

FootReviver insoles address plantar fasciitis through three mechanisms. The gel layer and targeted heel pad absorb impact during heel strike, reducing the shock transmitted to the plantar fascia. The arch support lifts your arch slightly, reducing how much the fascia has to stretch with each step. This helps distribute load more evenly across your foot, reducing the strain on the plantar fascia. By spreading pressure across a larger area, the insoles reduce the concentrated stress on the heel attachment point where micro-tears typically occur.

By reducing strain during the day, the fascia is less irritated by evening, which can lead to less tightness and pain when you take your first steps in the morning. These insoles reduce daily irritation so tissues can repair—they’re not instant pain relief. Most people notice gradual improvement over 2–4 weeks as inflammation settles.

Plantar fasciitis usually improves with a combination of approaches: rest from aggravating activities, calf and plantar fascia stretching, ice after activity, and gradual return to running. The fascia is under tension with every step—even walking around the house—so it’s hard to fully rest. This is why combining insoles with stretching, gradual activity, and appropriate footwear gives the best chance of sustained improvement. If left untreated, the fascia can develop scar tissue, making it stiffer and more prone to re-injury. If your pain isn’t improving after 4–6 weeks, or if it’s getting worse, see a physiotherapist or podiatrist for assessment. You may need imaging or a biomechanical assessment.

Shin Splints

Shin splints cause pain along the inner edge of your shin bone. They’re particularly common among runners, affecting a significant proportion of athletes and military recruits. The condition is often caused by sudden increases in training intensity, duration, or frequency, or by running on hard surfaces without adequate cushioning.

The muscles and tendons along your shin absorb shock with every footstrike. If they’re overloaded—often from ramping up mileage too quickly, running on concrete or tarmac, or wearing worn-out shoes—they pull repeatedly on the bone. This repeated pulling irritates the bone surface and the attachment points, causing inflammation and pain along the inner edge of your shin. Many runners notice their shin pain is worse on concrete than grass—concrete doesn’t absorb any shock, so your legs take the full impact.

You’ll typically feel tenderness, soreness, or pain along the inner side of your shin bone, sometimes with mild swelling in the lower leg. The pain worsens during and after exercise.

Shock-absorbing insoles reduce the impact forces that travel up your leg with every footstrike. When impact is reduced, your shin muscles and tendons don’t have to work as hard to absorb and control each footstrike, so they pull less forcefully on the bone. By cushioning the heel and forefoot and providing arch support, these insoles help lower the load on the muscles and tendons that attach to your shin bone. Lowering the impact on your shins means the muscles and tendons aren’t working as hard with every step, giving the bone surface a chance to settle.

Shin splints usually improve with rest, ice, gradual return to running, and addressing training errors—for example, not increasing mileage by more than 10% per week. Strengthening exercises for the calf and shin muscles can also help. If shin splints are ignored and you continue high-impact training, the repeated stress can progress to stress fractures—tiny cracks in the bone that require much longer recovery. If pain persists despite rest and insoles after 4–6 weeks, see a physiotherapist to rule out stress fractures.

Runner’s Knee (Patellofemoral Pain Syndrome)

Runner’s knee causes pain around or behind the kneecap. It’s one of the most common running injuries, caused by repetitive stress on the knee joint from running, jumping, squatting, or climbing stairs.

Repetitive impact from running travels up through your knee joint, putting stress on the cartilage under your kneecap. Cartilage is the smooth, slippery surface that lets your kneecap glide over the knee joint. When it wears down or becomes irritated, the surfaces rub more roughly, causing pain. If your foot rolls inward excessively or outward with each step, this creates twisting forces on your knee. When your foot rolls inward or outward, your shin bone rotates slightly, but your thigh bone doesn’t rotate as much. This creates a twisting stress across the knee joint, increasing the stress on the kneecap. Over time, this can lead to cartilage wear and pain. Cartilage has a limited blood supply, so it heals slowly. If you continue running without addressing the underlying causes—weak hips, poor foot control, inadequate cushioning—the irritation persists and can become chronic. Chronic cartilage irritation can lead to permanent changes in the joint surface, increasing the risk of early-onset arthritis.

You’ll typically feel pain around or behind the kneecap, especially when bending your knee. The pain worsens when walking, running, squatting, kneeling, or climbing stairs, and often appears after sitting for long periods with your knee bent.

By reducing the impact forces that travel up your leg and by controlling overpronation and supination via the firm base and heel cup, these insoles can help reduce the stress on your knee joint. The arch support also helps control how much your foot flattens with each step, which reduces the inward rotation of your shin and the twisting stress on your knee. This may help prevent runner’s knee from developing and reduce the risk of re-injury during activity if you already have it.

Runner’s knee usually improves with rest, ice, strengthening exercises for the quadriceps and hip muscles, and gradual return to running. Improvement is often gradual—expect several weeks of consistent wear before you notice a clear difference. If pain persists after 4–6 weeks, see a physiotherapist for assessment and a tailored exercise programme.

Metatarsalgia

Metatarsalgia is inflammation and pain in the ball of your foot, specifically around the metatarsal heads—the bony prominences at the base of your toes, just behind the ball of your foot. It’s common among runners, people who wear high heels or tight shoes, and people with high arches.

During forefoot loading—the phase of running when your body weight shifts onto the ball of your foot—the metatarsal heads take a lot of pressure. If this area isn’t cushioned, or if your shoes are too tight or have thin soles, you can develop inflammation and pain. High-impact activities like running and jumping increase the risk.

You’ll typically feel sharp, aching, or burning pain in the ball of your foot. It’s worse when standing, walking, or running—especially in tight shoes or high heels. You may feel like you’re walking on a pebble or marble.

The targeted metatarsal pads in these insoles provide extra cushioning under the ball of your foot as you roll forward. The pads sit just behind the metatarsal heads, lifting and supporting the arch of your forefoot so more of your weight is carried by the pad rather than the bony prominences. This reduces the pressure on the metatarsal heads and can help relieve pain and prevent further inflammation. If you’ve been running in flat insoles, you’ll notice the difference immediately—less burning pain under the ball of your foot.

Metatarsalgia usually improves with rest, ice, wearing wider shoes with good cushioning, and avoiding high heels. Metatarsalgia can be difficult to settle because you load the ball of your foot with every step—even walking. Cushioning and pressure redistribution help, but you may also need wider shoes and to avoid high heels or thin-soled footwear. If pain persists after 4–6 weeks, see a podiatrist for assessment.

Morton’s Neuroma

Morton’s neuroma is a thickening of the tissue around one of the nerves leading to your toes, usually between the third and fourth toes. Repeated pressure and irritation cause the nerve to develop scar tissue as a protective response, making it thicker and more painful. It causes sharp, burning pain in the ball of your foot and can make your toes feel numb or tingly.

Morton’s neuroma is often caused by repetitive pressure on the forefoot, tight or narrow shoes—especially high heels—or high-impact activities like running. The pressure irritates the nerve, causing it to thicken and become painful. If the pressure continues, the nerve thickening can worsen, making the pain more constant and severe.

You’ll typically feel sharp, burning pain in the ball of your foot, tingling or numbness in your toes, and a feeling like you’re standing on a fold in your sock or a pebble. It often eases when you take your shoes off and rest your feet.

The metatarsal pads in these insoles cushion the ball of your foot and help redistribute pressure away from the affected nerve, reducing the compression and irritation that caused the thickening. This can help reduce pain and prevent the neuroma from worsening.

Morton’s neuroma usually improves with rest, wearing wider shoes with good cushioning, avoiding high heels, and using metatarsal pads. If pain persists after several weeks, see a podiatrist for assessment and further treatment options.

Achilles Tendonitis

Achilles tendonitis is inflammation of the Achilles tendon—the thick band of tissue that connects your calf muscles to your heel bone. The tendon can stretch and recoil, but if the load is too great or too frequent, individual fibres tear, triggering inflammation and pain. It’s common among runners, especially those who suddenly increase their training intensity or distance, or who run on hills or uneven surfaces.

The Achilles tendon absorbs force with every footstrike and generates force during push-off. If the tendon is overloaded—often from ramping up mileage too quickly, running on hard surfaces, or having tight calf muscles—it can develop micro-tears and inflammation. Poor heel stability, where your foot rolls inward or outward excessively, can also increase strain on the Achilles tendon. The Achilles tendon, especially the mid-portion, has a relatively poor blood supply, which slows healing. Because the tendon is loaded with every step, it’s difficult to rest completely, so recovery can take weeks to months.

You’ll typically feel pain and stiffness along the Achilles tendon, especially in the morning or after rest. The pain worsens with activity, and you may notice swelling along the tendon or thickening of the tendon itself.

The heel cup in these insoles helps stabilise your heel, reducing excessive inward or outward rolling that can strain the Achilles tendon. When your heel is more stable and centred, your Achilles tendon pulls in a straighter line, reducing the twisting and bending forces that can irritate it. The shock-absorbing gel also reduces the impact forces that travel up through the tendon with every footstrike. Less jarring through the tendon with each footstrike means the micro-tears have a better chance to knit back together between runs.

Achilles tendonitis usually settles with rest, ice, calf stretching and strengthening exercises, and gradual return to running. Recovery can take weeks to months, because the tendon is loaded with every step. If pain persists or worsens after 4–6 weeks, see a physiotherapist for assessment and a tailored exercise programme.

Ankle Sprains

An ankle sprain is an injury to the ligaments that support your ankle, usually caused by rolling your ankle inward or outward. Ligaments are tough bands that hold bones together and limit how far a joint can move. When they’re stretched or torn, they can’t hold the ankle as firmly, so it tips more easily. Ankle sprains are common in sports that involve running, jumping, or quick direction changes. After an initial sprain, the ankle can remain weak and unstable, increasing the risk of re-injury.

After an ankle sprain, the ligaments may be stretched or partially torn, leaving the ankle less stable. If your heel rolls excessively inward or outward with each step, this puts extra stress on the healing ligaments and increases the risk of re-injury. Shock-absorbing insoles can help by reducing the impact forces that travel through the ankle and by providing heel stability to reduce excessive rolling.

The shaped heel cup in these insoles helps centre your heel in your shoe, reducing extreme inward or outward tipping. The shock-absorbing gel reduces the impact forces that travel through your ankle with every step. Reducing impact also means less jarring force through the healing ligaments with each step, giving them a calmer environment to repair. Together, these features can help reduce the risk of re-injury during activity.

Ankle sprains usually improve with rest, ice, compression, elevation, and gradual return to activity. Strengthening and balance exercises are important to restore stability. If you have recurrent ankle sprains or persistent instability after 4–6 weeks, see a physiotherapist for assessment—you may need a brace or specific exercises.

Arthritis (Osteoarthritis and Rheumatoid Arthritis)

Arthritis is inflammation of one or more joints, causing pain, stiffness, and swelling. The two most common types are osteoarthritis—wear-and-tear arthritis, where cartilage breaks down over time—and rheumatoid arthritis, an autoimmune condition where the immune system attacks the joints. With age and repetitive use, cartilage can wear down faster than the body can repair it, especially in weight-bearing joints. Both can affect the feet, ankles, knees, hips, and lower back.

Every time your foot strikes the ground, the impact travels up through your joints. If you have arthritis, this repetitive impact can worsen joint pain and accelerate cartilage wear. Shock-absorbing insoles reduce the peak forces that reach your joints, which may help reduce pain and slow the progression of cartilage damage.

The full-length gel cushioning and targeted heel and metatarsal pads absorb impact before it reaches your joints. The arch support and heel cup help distribute load more evenly, reducing stress on any one joint. This can help reduce pain during walking, standing, and running. This is most helpful for the joints in your feet, ankles, and knees—the areas that take direct impact. The benefit for hips and lower back is more indirect, through reduced force transmission up the leg. While insoles can’t reverse arthritis, reducing impact may help slow further cartilage wear and keep you more comfortable and active, which is important for maintaining joint health and overall mobility.

Arthritis is usually managed with a combination of approaches: weight management, low-impact exercise such as swimming or cycling, strengthening exercises, pain relief medication, and sometimes further treatment. Insoles are one part of management, not a cure. If your pain is severe or worsening, see a GP or rheumatologist for assessment.

Flat Feet and High Arches

Flat feet and high arches are variations in foot structure that can affect how your foot distributes load and absorbs shock. Flat feet spread load across the entire sole, but the arch structures—the plantar fascia and tendons—have to work harder to control the foot. High arches concentrate load on the heel and forefoot, with less midfoot contact to absorb shock. People with flat feet tend to overpronate, where the foot rolls inward excessively, while people with high arches tend to supinate, where the foot rolls outward, or have reduced shock absorption because the arch doesn’t flatten enough to absorb impact.

If your arches are very flat or very high, your foot may not distribute load evenly. This can increase stress on certain areas and increase the risk of injuries. When your arch collapses excessively with flat feet, your foot rolls inward more, increasing strain on the plantar fascia, Achilles tendon, and inner knee. When your arch is very high and rigid, your foot doesn’t absorb shock as well, concentrating stress on the heel and forefoot. This increases the risk of injuries like plantar fasciitis, shin splints, and stress fractures. Moderate arch support can help by improving load distribution and reducing strain on vulnerable areas.

The moderate arch support in these insoles accommodates a range of arch types—low, neutral, and higher arches—within a comfortable range of movement. The support is firm enough to lift a low arch slightly, but flexible enough to compress comfortably under a higher arch. The support helps distribute load more evenly across your foot, reducing strain on the plantar fascia and other structures. The firm base under the heel and arch also helps control overpronation and supination, reducing twisting forces on your ankle and knee.

If you have very flat feet or very high arches and need strong correction, you may benefit from a firmer orthotic insole rather than a gel-based shock-absorbing insole. If you have significant pain that doesn’t improve with these insoles after 3–4 weeks, or if your foot rolls excessively even with the insoles, you may benefit from a firmer, custom-made orthotic. A podiatrist can assess your foot mechanics and advise. If you’re unsure, ask a physiotherapist or podiatrist for advice.

Hip Pain

Hip pain can have many causes, including arthritis, bursitis—inflammation of the fluid-filled sacs around the hip joint—tendonitis, muscle strains, and referred pain from the lower back. In runners and people who spend long hours on hard surfaces, hip pain is often linked to repetitive impact and poor shock absorption.

Every footstrike sends force up through your ankle, shin, knee, and into your hip. Your hip joint has to absorb and stabilise against this force, and the muscles and tendons around the hip work harder to control your leg position with each step. If your foot doesn’t absorb enough of this shock, or if your foot rolls excessively inward or outward, creating twisting forces, your hip has to absorb more stress. When your foot rolls inward or outward, your shin rotates, which changes the angle of your knee, which in turn changes how your thigh bone sits in your hip socket. This altered alignment increases stress on the hip joint and surrounding muscles. Over time, this can lead to hip pain, especially in the muscles, tendons, and bursae around the hip joint.

By reducing the impact forces at the source—your foot—and by controlling overpronation and supination, these insoles can help reduce the stress that travels up to your hip. This may help reduce hip pain and prevent it from worsening.

Hip pain can have many causes—some related to foot mechanics, others to the hip joint itself, such as arthritis or bursitis, or surrounding muscles. If insoles don’t help after 3–4 weeks, the issue may be primarily in the hip rather than the foot. If your hip pain is severe, persistent, or getting worse despite wearing insoles, see a physiotherapist or GP for assessment. You may need specific exercises, manual therapy, or imaging to identify the underlying issue.

Lower Back Pain

Lower back pain is extremely common, affecting most people at some point in their lives. In runners and people who spend long hours on hard surfaces, lower back pain is often linked to repetitive impact, poor posture, weak core muscles, or biomechanical issues in the feet and legs.

Every footstrike sends force up through your ankle, shin, knee, hip, and into your lower back. Each footstrike sends a compression force up through your pelvis into your lower back. Your lumbar discs—the cushioning pads between your vertebrae—and facet joints—the joints between your vertebrae—absorb this compression, and your back muscles brace to keep you stable. If the impact is high and repetitive, these structures can become overloaded and painful. If your foot doesn’t absorb enough of this shock, or if your foot rolls excessively inward or outward, creating twisting forces, your lower back has to absorb more stress. Over time, this can lead to muscle fatigue, joint strain, and pain.

By reducing the impact forces at the source—your foot—and by controlling overpronation and supination, these insoles can help reduce the stress that travels up to your lower back. This may help reduce back pain and prevent it from worsening, especially if your back pain is linked to repetitive impact or biomechanical issues in your feet.

Most lower back pain is caused by issues in the back itself—discs, joints, muscles, or posture—rather than foot mechanics. Insoles can help if impact is a contributing factor, but if your pain doesn’t improve after 3–4 weeks, the primary issue is likely in your back and may need specific back-focused treatment. If your back pain is severe, persistent, or getting worse despite wearing insoles, see a physiotherapist or GP for assessment. You may need specific exercises, manual therapy, or imaging to identify the underlying issue. Insoles can help reduce impact-related back pain, but they’re not a substitute for core strengthening, posture correction, or treatment of underlying spinal problems.
