Insoles for Heel Pain & Heel Spurs
A complete guide to heel pain causes, how heel spurs actually form and what they mean, and which insole features genuinely reduce heel pain — versus which ones just feel good without helping.
Heel pain is one of the most common musculoskeletal complaints — second only to back pain in frequency. But “heel pain” is not a single condition. It’s a symptom with multiple possible causes, and the right insole depends entirely on which cause is driving it. An insole that helps plantar fasciitis heel pain is different from one that helps Achilles tendon heel pain, which is different again from one that helps fat pad atrophy.
This guide covers the most common causes of heel pain, how to distinguish between them, and which insole features address each one. It also covers heel spurs specifically — because heel spurs are widely misunderstood and the misconceptions lead people to buy the wrong treatment.
The Heel Spur Myth — What You Need to Know First
Heel spurs are calcium deposits that form on the heel bone, typically at the attachment point of the plantar fascia or the Achilles tendon. They show up on X-rays and look alarming — a pointed bony protrusion on the heel. They are routinely blamed for heel pain by patients and sometimes by clinicians.
The problem with this explanation is that research consistently shows heel spurs do not cause pain by themselves. Studies have found heel spurs in approximately 50% of people with no heel pain whatsoever — and in only about 10% more people with heel pain than without. The spur is a response to chronic tension on the tissue attachment — the body deposits calcium where connective tissue repeatedly pulls away from bone. The spur is a consequence of the mechanical problem, not the cause of the pain.
What this means practically: if you have been told you have a heel spur and that the spur is causing your pain, the treatment should still focus on reducing the tension on the plantar fascia or Achilles — not on the spur itself. An insole that addresses the mechanical root cause will relieve your pain whether or not a spur is present.
Surgery to remove heel spurs has very poor outcomes and is rarely recommended by podiatrists familiar with the evidence. The pain relief from insoles and conservative treatment comes from reducing mechanical stress on the tissue — which works whether or not a spur is present.
Common Causes of Heel Pain — and How to Distinguish Them
Plantar fasciitis (most common — ~70% of heel pain)
Pain at the bottom of the heel, worst with the first steps in the morning or after sitting. Eases after 10–15 minutes of walking, then returns with prolonged standing. Usually felt as a sharp, stabbing pain at the inner heel. See our dedicated Plantar Fasciitis guide for full detail.
Heel fat pad atrophy
The heel has a specialized fat pad that acts as a shock absorber. This pad thins with age — particularly after 50 — and can also atrophy from years of corticosteroid injections or in people with very low body fat. The pain is a deep, bruised aching sensation across the base of the heel rather than the sharp, point-specific pain of plantar fasciitis. It is worse on hard surfaces, eased by cushioned footwear, and does not follow the morning-worst pattern of fasciitis. Treatment focuses on cushioning rather than arch support.
Achilles tendinopathy
Pain at the back of the heel or just above it, where the Achilles tendon attaches to or inserts into the heel bone. Often accompanied by morning stiffness, swelling or thickening of the tendon, and pain that worsens with activity rather than easing after a warm-up. Insertional Achilles tendinopathy (pain at the heel attachment) benefits from heel elevation and cushioning. Mid-portion tendinopathy (pain 2–6cm above the heel) is less directly helped by insoles.
Retrocalcaneal bursitis
Inflammation of the bursa (fluid-filled sac) between the Achilles tendon and the heel bone. Pain and swelling at the back of the heel, aggravated by pressure from shoe heel counters. Treatment involves reducing pressure at the back of the heel — heel lifts and avoiding rigid-backed shoes.
Stress fracture of the calcaneus
Rare but important to not miss. Diffuse heel pain that worsens progressively with activity and doesn’t follow the morning-worst pattern. Often occurs after a sudden increase in activity. Requires medical evaluation and imaging — insoles are not the treatment for a stress fracture.
If your heel pain came on suddenly after a fall or impact, if it is associated with significant swelling and bruising, if it is severe at rest as well as with activity, or if it does not improve at all after 4 weeks of conservative treatment — get an X-ray. Stress fractures and other structural problems need to be ruled out before assuming a soft tissue cause.
Insole Features for Heel Pain — by Cause
| Cause | Primary Feature | Secondary Feature | Avoid |
|---|---|---|---|
| Plantar fasciitis | Firm arch support | Deep heel cup + slight heel lift | Soft gel-only insoles |
| Fat pad atrophy | Thick heel cushioning | Soft, conforming materials | Rigid insoles with minimal cushion |
| Achilles tendinopathy | Heel lift (6–10mm) | Rear cushioning, soft heel cup | Flat insoles, zero-drop shoes |
| Retrocalcaneal bursitis | Heel lift to reduce tendon angle | Reduce heel counter pressure | Stiff-backed shoes without lift |
Key Insole Features for Heel Pain
Heel Cups vs Full Insoles — Which to Choose
Heel cups are small inserts that fit only under the heel. They are inexpensive, fit in almost any shoe, and provide localized heel cushioning and containment. They are the right choice when your heel pain is isolated and your arch mechanics are normal or adequately supported by the shoe itself.
Full insoles address the entire foot — arch support, heel cup, and forefoot cushioning together. They are the right choice when your heel pain is driven by arch mechanics (overpronation, flat feet) or when you need comprehensive support across the foot. For plantar fasciitis specifically, full insoles consistently outperform heel cups because they address the arch collapse that is the primary driver of fascia tension.
If you’re unsure, start with a full insole. Heel cups are a reasonable choice for isolated fat pad atrophy or mild Achilles tendon issues where the arch is not a contributing factor.
Heel Pain and Shoe Choice
An insole works inside a shoe — and the shoe matters as much as the insole for heel pain management.
The most important shoe feature for heel pain is a firm, supportive heel counter — the stiff section at the back of the shoe that cups the heel. Squeeze the heel counter of your shoe between your fingers. If it collapses easily, the shoe is providing no heel stability and your insole is working without structural backup. For heel pain, the heel counter should be firm enough to resist hand pressure.
Avoid completely flat shoes — flip flops, minimalist shoes, worn-out athletic shoes — during recovery. Even brief periods of unsupported footwear can accumulate enough load on the fascia to set back progress. If you need low-profile footwear, Birkenstock sandals (with their contoured footbed) are one of the few flat-looking options that provide adequate arch support for most people.
For people with wide feet, getting the shoe width right matters directly for heel pain management — a too-narrow shoe compresses the foot and alters gait mechanics, increasing heel impact. See our guide on Wide Feet if you suspect width is a contributing factor.
Seek professional evaluation if heel pain has not improved after 6–8 weeks of correct insoles and stretching, if pain is severe enough to cause limping or alter your gait, if you have numbness or tingling accompanying the heel pain (possible nerve entrapment), if the pain came on suddenly after an impact, or if you have diabetes. A podiatrist can perform a biomechanical assessment, order imaging if needed, and recommend injection therapy or shockwave therapy for resistant cases.
Is Your Heel Pain Plantar Fasciitis?
About 70% of heel pain is plantar fasciitis-related. If your pain is worst in the morning with first steps, see our dedicated plantar fasciitis guide for the full treatment approach.

Heel spurs themselves rarely cause pain directly. Studies consistently show that approximately 50% of people with heel spurs have no pain, and the incidence of spurs is only marginally higher in people with heel pain than in those without. The spur is a calcium deposit that forms in response to chronic tension at a connective tissue attachment — it’s a consequence of the mechanical problem, not the cause of pain. Treatment should focus on reducing the mechanical stress driving the condition, not on the spur itself.
For plantar fasciitis heel pain — the most common type — the fastest relief combination is: a supportive insole with firm arch support and deep heel cup worn consistently in all footwear, calf and plantar fascia stretching first thing in the morning before standing, and avoiding flat unsupported footwear entirely. The morning stretch before first steps makes the biggest immediate difference for the characteristic morning pain. Most people notice meaningful improvement within 2–4 weeks of this combined approach.
Gel heel cups provide good cushioning and help with fat pad atrophy and mild impact-related heel pain. They are less effective for plantar fasciitis because they don’t address the arch mechanics that are the primary driver of fascia tension. If your heel pain is the morning-worst, sharp-stabbing type characteristic of plantar fasciitis, a full insole with firm arch support will provide better results than a gel heel cup alone. Gel heel cups are best for people with heel pain driven by fat pad thinning or general impact absorption needs.
Yes — footwear is one of the primary contributing factors to heel pain. Shoes that are completely flat (no heel elevation), have no arch support, have a worn-out or collapsed heel counter, or are too narrow (altering foot mechanics) all increase the load on the plantar fascia and heel structures. Switching to supportive footwear — even without insoles — often produces significant improvement. Insoles work best as an addition to appropriate footwear, not as a replacement for it.
Complete rest is generally not recommended. The plantar fascia and heel structures need appropriate loading to stimulate healing — total rest removes the mechanical stimulus for repair. What helps is relative rest — reducing high-impact activity (running, jumping, prolonged standing on hard floors) while maintaining walking in supportive footwear. Swimming and cycling are good low-impact alternatives that maintain fitness without heel loading. Return to full activity gradually once pain has significantly reduced.
For plantar fasciitis and general heel pain, a heel cup depth of at least 12–14mm provides meaningful fat pad containment. For heel elevation to reduce Achilles tension, a lift of 6–10mm is the effective range — more than this can create instability and is rarely needed. The overall insole thickness matters for shoe fit — a full insole should be thick enough to provide support but slim enough to fit comfortably in the shoe without creating tightness. If adding an insole makes your shoe feel tight, you may need a wider shoe rather than a thinner insole.
