Heel Tenderness: What Every Step Is Telling You — Causes, Diagnosis, Treatment & the Best Shoes for 2026

Plantar fasciitis involves micro-tearing and inflammation of the plantar fascia — a thick band of connective tissue that runs from the heel bone to the toes. It is the most common cause of inferior heel tenderness, accounting for roughly 73% of all heel pain cases seen in primary care. Pain is typically sharp and localised under the heel, especially with the first steps in the morning or after prolonged sitting. The pain often eases after a few minutes of walking, then returns after extended standing or activity.

Risk factors: High-archer feet, flat feet, tight Achilles tendons, prolonged standing, sudden increase in activity, and unsupportive footwear. Treatment includes stretching, orthotics, night splints, and activity modification.

Achilles tendinopathy affects the tendon that attaches the calf muscles to the heel bone. It presents as tenderness, stiffness, and sometimes swelling at the back of the heel, typically 2–6 cm above the insertion point on the calcaneus. Unlike plantar fasciitis, the pain is most noticeable during activity — especially pushing off the foot while walking, running, or climbing stairs — and may feel better at rest. Morning stiffness lasting more than 30 minutes is common.

It is often caused by overuse, tight calf muscles, excessive pronation, or a sudden increase in training intensity. Eccentric heel-drop exercises are the gold-standard rehabilitation approach. In chronic cases, doppler ultrasound may reveal neovascularisation and tendon thickening.

A stress fracture of the calcaneus (heel bone) typically produces a deep, aching pain that worsens with weight-bearing activity and persists even at rest. Unlike soft-tissue causes, the tenderness is usually directly over the bone, and the heel may feel warm or swollen. It is most common in runners, military recruits, and individuals who suddenly increase their training volume or intensity. Risk is also elevated in people with osteoporosis, vitamin D deficiency, or female athlete triad (low energy availability, menstrual dysfunction, low bone mineral density).

Diagnosis is often confirmed by MRI or CT, as X-rays may not show a stress fracture in the first 2–3 weeks. Treatment requires strict non-weight-bearing or limited weight-bearing for 4–8 weeks, followed by gradual return to activity.

Retrocalcaneal bursitis is inflammation of the bursa — a fluid-filled sac — located between the Achilles tendon and the heel bone. It produces tenderness and swelling at the back of the heel, just above the insertion point of the Achilles. The pain is often described as a squeezing or pinching sensation behind the heel, and it worsens with activities that involve repetitive ankle motion, such as running uphill, jumping, or wearing tight-backed shoes. Squeezing the sides of the posterior heel elicits sharp pain (the “squeeze test”).

Overlapping with Achilles tendinopathy is common. Treatment includes ice, NSAIDs, activity modification, heel lifts, and in persistent cases, corticosteroid injection (performed with ultrasound guidance to avoid the Achilles tendon).

The heel fat pad is a specialised layer of adipose tissue that acts as a shock absorber. With age, high-impact activity, or certain medical conditions, this pad can thin, lose elasticity, or shift position — leading to a sensation of “walking on bone.” Tenderness is typically central under the heel and is accompanied by a feeling of hardness or lack of cushioning. Unlike plantar fasciitis, the pain does not improve with a few minutes of walking; it often worsens as the day progresses.

Heel fat pad syndrome is more common in older adults (60+), long-distance runners, and individuals with diabetes or corticosteroid overuse. Treatment focuses on restoring cushioning through viscoelastic heel cups, silicone gel pads, and shock-absorbing footwear.

Tarsal tunnel syndrome involves compression of the posterior tibial nerve (or its branches, including the medial calcaneal nerve) as it passes through a fibro-osseous tunnel on the inside of the ankle. It produces burning, tingling, or electric-shock sensations in the heel, arch, and sometimes the toes. The tenderness is often medial (inner side) or diffuse across the heel, and symptoms may be worse at night or after prolonged standing. A positive Tinel’s sign (tapping over the tarsal tunnel reproduces symptoms) is a key clinical finding.

Causes include flat feet (pronation), ankle sprains, varicose veins, ganglions, or space-occupying lesions. Treatment may include orthotics to correct pronation, nerve gliding exercises, anti-inflammatory medication, and in refractory cases, surgical decompression.

Heel tenderness can sometimes be a presenting symptom of systemic disease. Seronegative spondyloarthropathies — including ankylosing spondylitis, psoriatic arthritis, and reactive arthritis — commonly cause enthesitis (inflammation at tendon or ligament insertion points) at the heel. This typically produces tenderness at both the plantar fascia insertion and the Achilles insertion, often with morning stiffness lasting more than 30 minutes. Gout can affect the heel (though less commonly than the big toe), producing sudden, intense pain, redness, and swelling. Rheumatoid arthritis may involve the subtalar joint, causing diffuse heel pain and stiffness. Diabetes can predispose to heel fat pad atrophy, peripheral neuropathy, and increased risk of infection (including calcaneal osteomyelitis).

If heel tenderness is bilateral, accompanied by other joint pain, skin changes, or systemic symptoms (fever, fatigue, weight loss), a rheumatological or endocrinological evaluation is warranted.

The most common cause is plantar fasciitis, accounting for approximately 73% of all heel pain cases. It involves inflammation of the plantar fascia — the connective tissue band that runs from the heel to the toes — and typically produces sharp pain under the heel with the first steps in the morning or after prolonged sitting.

No — heel tenderness is a symptom, while plantar fasciitis is one specific cause of that symptom. Heel tenderness can also result from Achilles tendinopathy, heel fat pad atrophy, calcaneal stress fracture, retrocalcaneal bursitis, tarsal tunnel syndrome, or systemic conditions like seronegative spondyloarthropathy. An accurate diagnosis is essential for effective treatment.

A calcaneal stress fracture typically produces deep, persistent pain that does not go away with rest, is localised directly over the bone, and worsens with weight-bearing. The “hop test” — hopping on the affected foot reproduces sharp pain — is a useful clinical sign. If you suspect a stress fracture, seek medical evaluation with imaging (X-ray, MRI, or CT) and avoid weight-bearing until cleared by a clinician.

Yes — footwear is one of the most effective modifiable factors for heel tenderness. Shoes with a firm heel counter, adequate arch support, appropriate drop, and sufficient cushioning can reduce strain on the plantar fascia and Achilles, offload the heel fat pad, and correct biomechanical issues like overpronation. Wearing unsupportive shoes (flip-flops, worn-out trainers, flat ballet flats) is a common factor in both the development and persistence of heel tenderness.

For persistent heel tenderness (>8–12 weeks of conservative care), the best next step depends on the cause. Options include physical therapy, extracorporeal shockwave therapy (ESWT), platelet-rich plasma (PRP) injections, or custom orthotics. Corticosteroid injections can provide short-term relief but are not a long-term solution due to risk of fat pad atrophy and tendon rupture. Surgery is reserved for the small minority who fail all non-surgical treatments. Always consult a podiatrist or sports medicine physician to tailor the approach to your specific condition.

It depends on the cause and severity. Mild plantar fasciitis may allow continued walking with modified activity and supportive shoes. Moderate to severe pain, especially with a suspected stress fracture or Achilles rupture, requires rest and medical evaluation. As a general rule: if walking causes pain that lingers after you stop, or if you are limping, reduce your activity and seek guidance. Low-impact alternatives (swimming, cycling, elliptical) can maintain fitness while the heel recovers.

Many mild cases of heel tenderness — especially acute plantar fasciitis — do resolve with simple measures like rest, ice, stretching, and better footwear. However, without addressing the underlying cause (tight calves, unsupportive shoes, training errors, biomechanical issues), the problem often recurs or becomes chronic. The average time to full recovery for plantar fasciitis with proper treatment is 6–12 months. Early, consistent intervention leads to faster outcomes.

Start with your primary care physician or a podiatrist (foot specialist). A podiatrist can perform a focused clinical exam, order imaging if needed, and provide orthotics or injections. If the cause is suspected to be systemic (inflammatory arthritis, gout, diabetes-related), your primary care physician may refer you to a rheumatologist or endocrinologist. For sports-related cases, a sports medicine physician or physical therapist with expertise in lower limb conditions is ideal.
