Inner Heel Pain When Wearing Shoes: Tarsal Tunnel, Posterior Tibial Tendonitis, Plantar Fasciitis, or Shoe Pressure?

Inner heel pain when wearing shoes can be surprisingly frustrating because the pain may not appear when you are barefoot or wearing slippers. You may feel fine at home, but as soon as you wear closed shoes, the inside of the heel starts hurting, burning, rubbing, or feeling tender to touch. This type of pain can come from something simple, such as shoe pressure over a sensitive bony or soft tissue area, but it can also point to conditions such as tarsal tunnel syndrome, posterior tibial tendonitis, plantar fasciitis, or irritation around the inner ankle and heel.

The key is to understand where exactly the pain is, what kind of pain it is, and what makes it worse. Pain that feels like burning, tingling, or electric shock may suggest nerve compression such as tarsal tunnel syndrome. Pain along the inside of the ankle and arch may suggest posterior tibial tendonitis. Sharp pain under the heel, especially with the first steps in the morning, is more typical of plantar fasciitis. Pain that happens mainly with a specific shoe may simply be due to pressure, poor fit, hard heel counters, or lack of cushioning.

This article explains the most common causes of inner heel pain when wearing shoes, how to tell them apart, what you can try at home, and when you should see a doctor.

Inner heel pain usually refers to pain on the medial side of the heel, which is the side of the heel closer to the other foot. Some people describe it as pain below the inner ankle bone, pain on the inside border of the heel, pain where the arch starts, or pain near the back-inner part of the heel.

This area contains several important structures, including the heel bone, the plantar fascia, the posterior tibial tendon, small ligaments, blood vessels, and the tibial nerve as it passes through the tarsal tunnel. Because several structures are close together, the pain can feel confusing. One person may say “heel pain,” another may say “ankle pain,” and another may describe “arch pain,” even though the source may be in the same general region.

A useful first step is to ask: Is the pain more like pressure, stabbing, pulling, burning, or tingling? The pain quality often gives a clue.

If your inner heel pain is worse in shoes but better in slippers, the shoe itself may be part of the problem. Closed shoes can compress the heel, change foot mechanics, restrict ankle motion, or press directly on an already irritated area.

Common shoe-related reasons include:

• Hard heel counters pressing on the inner heel.
• Narrow shoes squeezing the heel or arch.
• Poor arch support increasing strain on the plantar fascia or posterior tibial tendon.
• Worn-out soles changing foot alignment.
• Shoes with stiff edges rubbing below the inner ankle.
• A raised seam, insole edge, or orthotic pressing into the heel.
• A shoe that fits well in length but is too narrow at the heel or midfoot.

This does not always mean the shoe is the only cause. Shoes may simply expose an underlying problem. For example, a person with early posterior tibial tendon irritation may feel little discomfort barefoot but develop pain when a shoe changes foot position or pushes the tendon against the inner ankle area.

Tarsal tunnel syndrome occurs when the tibial nerve is compressed or irritated as it passes through a narrow space on the inside of the ankle called the tarsal tunnel. This tunnel lies behind and below the inner ankle bone. When the nerve is irritated, pain can travel into the heel, arch, sole, or toes.

Tarsal tunnel syndrome is important to consider when inner heel pain has a nerve-like quality. The pain may feel like burning, pins and needles, numbness, electric shock, or shooting pain. Symptoms may worsen with prolonged standing, walking, or shoes that press on the inside of the ankle and heel. Cleveland Clinic notes that tarsal tunnel syndrome can cause pain, burning, or tingling in the bottom of the feet and toes due to tibial nerve damage or compression ^[1]. StatPearls also describes sharp, shooting foot pain, plantar numbness, tingling, burning, and pain radiating from the tarsal tunnel into the arch and sole ^[2].

Tarsal tunnel syndrome may cause:

• Burning pain on the inner heel or sole.
• Tingling in the arch, heel, or toes.
• Numbness under the foot.
• Pain that worsens with walking or standing.
• Symptoms that may be worse at night.
• Shooting pain from the inner ankle into the heel or foot.
• Discomfort when shoes press below the inner ankle bone.

Some people also feel as if they are walking on pebbles, sand, or a folded sock. The pain may be difficult to localize because nerves can refer symptoms away from the exact point of compression.

Shoes can worsen tarsal tunnel symptoms if they are tight around the ankle, compress the medial heel, or force the foot into excessive pronation. If the arch collapses inward while walking, it may increase traction or irritation around the tibial nerve. In some people, flat feet, swelling, tendon problems, varicose veins, or a ganglion cyst can contribute to nerve compression.

If your pain is accompanied by numbness, tingling, burning, or electric sensations, do not ignore it. Nerve symptoms usually need more careful evaluation than ordinary shoe rubbing.

Posterior tibial tendonitis is another common reason for pain on the inside of the ankle and heel. The posterior tibial tendon helps support the arch of the foot and assists with walking. When this tendon becomes irritated, inflamed, or weakened, pain often appears along the inner ankle and arch.

Cleveland Clinic explains that posterior tibial tendonitis causes pain and tenderness along the arch or inside of the foot and ankle. If the tendon weakens over time, it can lead to posterior tibial tendon dysfunction, flattening of the foot, and inward rolling of the ankle ^[3]. The American Academy of Orthopaedic Surgeons also describes posterior tibial tendon dysfunction as a condition that can progressively affect the arch and cause adult-acquired flatfoot ^[4].

Posterior tibial tendonitis may cause:

• Pain behind or below the inner ankle bone.
• Pain extending toward the inner heel or arch.
• Tenderness when pressing along the tendon.
• Swelling on the inside of the ankle.
• Pain that worsens with walking, stairs, or standing.
• Difficulty standing on tiptoe on the affected foot.
• A feeling that the arch is weak or collapsing.
• Pain when wearing shoes that press along the tendon.

This condition may begin as mild discomfort but can worsen if the tendon is overloaded repeatedly. People with flat feet, high body weight, sudden increase in walking, poor footwear, or jobs requiring long standing may be more prone to this problem.

One simple clue for posterior tibial tendon problems is difficulty doing a single-leg heel raise. If you cannot rise onto the toes of the painful foot, or if it causes inner ankle and arch pain, posterior tibial tendon dysfunction becomes more likely. This is not a formal diagnosis, but it is a useful sign to discuss with a clinician.

Shoes without enough arch support can allow the foot to roll inward, increasing strain on the posterior tibial tendon. On the other hand, some stiff shoes or poorly fitted orthotics may press directly on the painful tendon area. This is why some people feel worse in certain shoes but better in slippers or supportive sandals.

A supportive shoe with a stable heel counter and proper arch support may help, but if the shoe is too tight at the inner ankle, it may worsen pain. The balance between support and pressure matters.

Plantar fasciitis is one of the most common causes of heel pain. It involves irritation of the plantar fascia, the thick band of tissue that runs from the heel toward the toes and supports the arch. Although plantar fasciitis is often felt under the heel, many people feel the pain more toward the inner-bottom side of the heel where the plantar fascia attaches.

Mayo Clinic describes plantar fasciitis pain as commonly being stabbing and often worst with the first steps in the morning. The pain may ease with movement but return after long standing or after getting up from sitting ^[5]. Mayo Clinic also notes that many people recover over several months with conservative care such as icing, stretching, and modifying activities that trigger symptoms ^[6].

Plantar fasciitis may cause:

• Sharp pain under the heel.
• Pain near the inner-bottom part of the heel.
• Worst pain with the first steps after waking.
• Pain after sitting and then standing.
• Pain after long standing or walking.
• Tenderness when pressing the bottom-inner heel.
• Tightness in the calf or arch.

Unlike tarsal tunnel syndrome, plantar fasciitis usually does not cause tingling, numbness, or electric shock sensations. Unlike posterior tibial tendonitis, it usually hurts more under the heel than behind the inner ankle.

Shoes with thin soles, poor cushioning, worn-out support, or hard insoles can worsen plantar fasciitis. The American Academy of Orthopaedic Surgeons advises avoiding shoes with little padding or thin, hard soles and notes that heel cups, heel lifts, or heel wedges may provide support in some cases ^[7].

People with plantar fasciitis often feel worse walking barefoot on hard floors. However, some people feel better in slippers because slippers reduce direct pressure on the painful heel area. The problem is that soft slippers may give temporary relief but may not provide enough arch support for long-term recovery.

Sometimes inner heel pain when wearing shoes is exactly what it feels like: pressure from the shoe. This is especially likely if pain occurs only with one pair of shoes, starts shortly after wearing a new pair, or improves quickly when the shoe is removed.

Shoe pressure is more likely if:

• The pain is very localized to one pressure point.
• There is redness, rubbing, callus, blistering, or skin irritation.
• Pain starts soon after putting on a specific shoe.
• Pain disappears when switching shoes.
• There is no morning first-step pain.
• There is no numbness, tingling, or burning.
• Pressing the painful spot reproduces the exact pain.

Shoes can cause pain through a stiff heel counter, tight heel cup, narrow midfoot, hard insole edge, uneven seam, or poor arch contour. In some cases, an insole or orthotic that is meant to help may actually press into the inner heel or arch and create pain.

Run your hand inside the shoe and feel for rough seams, hard edges, raised stitching, an uneven insole, or a ridge near the inner heel. Compare the painful side with the other shoe. Remove the insole and check whether it is folded, worn down, or raised at the edge. Also check whether the shoe heel is tilted or worn unevenly.

If the problem is shoe pressure, changing footwear may solve the issue. If pain continues even after changing shoes, an underlying condition is more likely.

Although a doctor or podiatrist is the best person to diagnose persistent heel pain, the following symptom patterns can help you understand what may be happening.

If the pain is burning, tingling, numb, or electric, think about tarsal tunnel syndrome.

If the pain is along the inside ankle and arch, especially with weakness or flattening of the arch, think about posterior tibial tendonitis.

If the pain is sharp under the heel and worst with the first steps in the morning, think about plantar fasciitis.

If the pain occurs only in one shoe and matches a pressure point, think about shoe pressure.

If there is swelling, warmth, severe tenderness, inability to bear weight, or pain after injury, you should get medical evaluation rather than assuming it is a routine heel problem.

Not every case of inner heel pain is caused by tarsal tunnel syndrome, posterior tibial tendonitis, plantar fasciitis, or shoe pressure. Other possibilities include:

• Heel fat pad irritation.
• Stress fracture of the heel bone.
• Inflammatory arthritis.
• Insertional Achilles tendon problems.
• Medial calcaneal nerve irritation.
• Bursitis.
• Skin lesions, corns, calluses, or blisters.
• Referred pain from the lower back.
• Diabetic nerve pain.

This is why persistent or worsening pain should not be self-diagnosed for too long. A clinician may examine foot alignment, tendon strength, nerve sensation, gait, footwear, and areas of tenderness. Imaging or nerve tests may be needed in selected cases.

For mild inner heel pain without numbness, severe swelling, injury, or inability to walk, conservative steps may help.

Start with the simplest step: stop wearing the shoe that triggers the pain. Try a shoe with a wider heel and midfoot, soft but supportive cushioning, and enough arch support. Avoid very flat, thin, hard-soled shoes. Also avoid shoes that press under the inner ankle.

If your pain improves quickly with a shoe change, shoe pressure may have been a major factor.

A soft heel cup or cushioned insole may help plantar heel pain. However, if you suspect tarsal tunnel syndrome or posterior tibial tendonitis, avoid any insert that presses aggressively into the inner arch or ankle. Orthotics should support the foot, not create a new pressure point.

Gentle calf stretching and plantar fascia stretching may help plantar fasciitis and general heel tightness. Stretching should feel like tension, not sharp pain. Mayo Clinic includes stretching and activity modification among common conservative measures for plantar fasciitis ^[6].

If pain started after increased walking, running, stair climbing, or standing, reduce the aggravating activity for a few days. Switch to lower-impact activity if needed. Do not push through sharp heel pain or nerve-like burning.

Icing for short periods may reduce pain after walking or standing, especially in plantar fasciitis or tendon irritation. Do not apply ice directly to the skin.

If pain is along the inner ankle and arch, supportive shoes or an ankle brace may reduce strain. However, if there is progressive arch flattening, difficulty walking, or inability to do a heel raise, medical evaluation is important.

You should see a doctor, podiatrist, or orthopedic foot and ankle specialist if:

• Pain lasts more than one to two weeks despite changing shoes and reducing activity.
• Pain is worsening.
• You have burning, tingling, numbness, or electric shock sensations.
• You have weakness in the foot.
• You cannot stand on your toes on the painful side.
• You notice the arch collapsing or the ankle rolling inward.
• There is swelling, redness, warmth, or severe tenderness.
• You cannot bear weight normally.
• Pain started after a fall, twist, or injury.
• You have diabetes, nerve disease, circulation problems, or inflammatory arthritis.
• You have night pain, fever, unexplained weight loss, or pain that is not related to activity.

Nerve symptoms deserve particular attention because prolonged nerve compression can sometimes become harder to treat if ignored. Tendon dysfunction also should not be neglected because posterior tibial tendon problems can progress and alter foot structure over time.

A doctor will usually begin with a history and physical examination. They may ask where the pain is, when it started, which shoes worsen it, whether there is morning pain, whether there is tingling or numbness, and whether activity makes it better or worse.

The examination may include pressing along the plantar fascia, tapping over the tarsal tunnel to check for nerve irritation, testing sensation, checking posterior tibial tendon strength, observing the arch, and asking you to walk or rise onto your toes.

Imaging such as X-rays, ultrasound, or magnetic resonance imaging may be used if a stress fracture, tendon tear, mass, arthritis, or other structural problem is suspected. Nerve conduction studies may be considered when tarsal tunnel syndrome is suspected, although diagnosis is often based on the full clinical picture.

Treatment should match the underlying cause.

For plantar fasciitis, treatment often includes supportive footwear, heel cushioning, stretching, icing, activity modification, physical therapy, and sometimes night splints. Most people improve with conservative care over time ^[6].

For posterior tibial tendonitis, treatment may include rest from aggravating activity, supportive shoes, arch support, bracing, physical therapy, anti-inflammatory measures when appropriate, and medical monitoring if the arch is changing. More advanced posterior tibial tendon dysfunction may need specialized bracing or surgical consultation.

For tarsal tunnel syndrome, treatment may include reducing pressure on the nerve, changing footwear, managing swelling, correcting foot mechanics, physical therapy, orthotics when appropriate, anti-inflammatory measures, or further treatment if a structural cause is compressing the nerve. Cleveland Clinic notes that nonsurgical treatment often decreases symptoms in tarsal tunnel syndrome ^[1].

For shoe pressure, treatment may be as simple as changing shoes, removing a problematic insole, using padding, widening the shoe, or avoiding stiff heel counters. However, if a shoe repeatedly triggers pain in the same area, do not keep wearing it and hoping the foot will “adjust.”

Choose shoes with enough width in the heel and midfoot.

Avoid hard heel counters that dig into the inner heel.

Make sure the insole edge does not press into the arch.

Replace worn-out shoes.

Avoid very flat shoes if you have plantar fasciitis or posterior tibial tendon strain.

Avoid overly soft, unsupportive footwear for long walking.

Try shoes later in the day when feet may be slightly larger.

Wear socks that reduce friction and do not bunch up.

Check whether pain appears only with one shoe model or all closed shoes.

If using orthotics, make sure they are not creating a hard pressure point.

The best shoe is not always the most cushioned shoe. For some people, too much softness allows the foot to collapse inward. For others, too much stiffness creates direct pressure. The right footwear should reduce both strain and compression.

Mild shoe pressure can improve quickly once the irritating shoe is removed. Mild plantar fasciitis or tendon irritation can also improve with early care, better footwear, stretching, and activity modification. However, symptoms that persist, worsen, or include nerve features should be assessed.

Ignoring inner heel pain can lead to compensation. You may start walking differently to avoid pain, which can trigger knee, hip, back, or opposite foot discomfort. Early attention is usually easier than treating a chronic problem.

Inner heel pain when wearing shoes can come from several different causes. Tarsal tunnel syndrome is more likely when the pain burns, tingles, shoots, or causes numbness. Posterior tibial tendonitis is more likely when pain follows the inside of the ankle and arch, especially with weakness or flattening of the arch. Plantar fasciitis is more likely when pain is sharp under the heel and worst with the first steps in the morning. Shoe pressure is more likely when one specific shoe creates a localized painful spot that improves after removing the shoe.

A simple shoe change may solve the problem in some cases, but persistent inner heel pain should not be ignored. If you have nerve symptoms, swelling, worsening pain, arch collapse, or difficulty walking, get a proper medical evaluation so the correct cause can be treated early.
