From the anatomy of a heel spur to effective conservative therapies, shockwave options, and the best footwear for lasting relief — everything you need to stop the pain.
What Is a Heel Spur? Understanding the Bony Growth on Your Heel
A heel spur (also called a calcaneal spur) is a calcium deposit that forms a bony outgrowth on the underside of the heel bone. It develops over months or years, often at the attachment point of the plantar fascia. While many people assume a heel spur is the direct cause of sharp heel pain, the relationship is more nuanced.
The classic symptom of a painful heel spur is a sharp, stabbing pain under the heel — especially with the first steps in the morning or after long periods of rest. The pain may subside after walking a bit but can return after prolonged standing or exercise. Diagnosis is typically made via X-ray, which reveals the bony projection (often 0.5 to 1.5 cm in length). However, many people with heel spurs on X-ray have zero symptoms, which is why clinicians focus on the inflammation of the plantar fascia and surrounding soft tissues.
If you have persistent heel pain for more than two weeks, redness, swelling, or difficulty walking, consult a podiatrist or orthopedic specialist. A heel spur can sometimes mimic a stress fracture or even an infection.
What Really Causes Heel Spurs — and What Doesn’t
Heel spurs develop from repetitive microtrauma at the insertion of the plantar fascia on the calcaneus. The body responds by depositing calcium, which eventually forms a spur. The main risk factors include:
- Biomechanical issues: Flat feet (overpronation) or very high arches put extra strain on the heel.
- Repetitive high-impact activities: Running, jumping, or prolonged standing on hard surfaces.
- Improper footwear: Shoes with inadequate arch support, thin soles, or worn-out cushioning.
- Obesity: Excess body weight increases load on the heel.
- Age: Most common in people 40–60 years old, due to reduced fat pad elasticity and longer recovery from microtrauma.
A widespread misconception is that heel spurs are caused by “bone spurs” from arthritis or a calcium-rich diet. Neither is true. Heel spurs are mechanical in origin, not dietary. And contrary to older beliefs, a heel spur does not “dig into” the foot like a thorn — most pain actually comes from inflammation of the plantar fascia, not the spur itself.
“The heel spur is often an innocent bystander. The real culprit is the inflamed fascia. Treat the fascia, and the spur often becomes symptom-free.”
— Dr. James W. Brodsky, Foot & Ankle Specialist
Proven Treatments for Heel Spurs: What Works in 2026
Treatment for a symptomatic heel spur mirrors that of plantar fasciitis, because the underlying cause is almost identical. Most people (up to 90%) improve with conservative care. Here’s the modern, step‑wise approach:
Platelet‑rich plasma (PRP) injections and prolotherapy are gaining traction. Early studies suggest PRP may be as effective as ESWT for chronic cases, with lower recurrence rates. Ask your podiatrist if you’re a candidate.
Best Shoes for Heel Spurs — What to Look For & Top Picks
The right footwear is arguably the single most impactful self‑care step for heel spur pain. Here are the five key shoe features to prioritize, along with recommended models for 2026.
Vionic Walker — Built‑in orthotic with deep heel cup. Excellent arch support. Run slightly heavy but extremely stable.
Brooks Glycerin 21 — Plush, balanced cushioning. Great for longer runs. Heel counter is snug but not rigid.
5 Common Heel Spur Myths Busted
No evidence links dietary calcium to spur formation. Heel spurs are mechanical — the result of repetitive traction on the bone, not excess calcium in the blood.
True. Up to 50% of people with visible heel spurs on X-ray have no heel pain. Pain usually comes from the associated plantar fasciitis, not the spur itself.
Surgery is rarely needed. Over 90% of people improve with conservative treatments like stretching, orthotics, and proper shoes. Surgery is only considered after 6–12 months of failed conservative care.
Partially true. Walking barefoot on hard surfaces increases strain on the plantar fascia. But walking on soft grass or sand with gradual adaptation can be fine. The key is transitioning slowly and listening to your pain.
Not at all. Many heel spurs stop growing after the initial inflammation subsides. With proper management, pain often resolves even though the spur remains visible on X-ray.
Frequently Asked Questions About Heel Spurs
Can a heel spur go away on its own?
The bone spur itself will not dissolve or disappear without surgical removal. However, the pain and inflammation can go away completely with conservative care. Many people live pain‑free for years with a visible spur.
Is heat or ice better for heel spur pain?
Ice is better for acute pain and inflammation — roll a frozen water bottle under your foot for 10–15 minutes. Heat can be used before stretching to relax the calf and plantar fascia, but don’t apply heat if there’s active swelling.
Can I still run with a heel spur?
It depends on your pain level. If running causes sharp pain, take a break and cross‑train (cycling, swimming). Once pain subsides, gradually return with proper shoes, orthotics, and a running surface that isn’t too hard (avoid concrete). Many elite runners manage heel spurs with good footwear and physiotherapy.
Do anti‑inflammatory pills really help?
Oral NSAIDs (ibuprofen, naproxen) can reduce short‑term inflammation and pain, but they do not address the underlying mechanical cause. Long‑term use is not recommended due to potential gastrointestinal and kidney side effects. Topical NSAIDs (diclofenac gel) are a gentler alternative.
What is the difference between a heel spur and plantar fasciitis?
Plantar fasciitis is inflammation of the thick tissue band (fascia) that runs from the heel to the toes. A heel spur is a bony growth at the heel bone’s attachment point. They often coexist — about 80% of heel spur patients also have plantar fasciitis — but they are separate conditions. The treatment is nearly identical because the root cause (tension and microtears at the insertion) is the same.
