Haglund’s deformity is a bony bump at the back of the heel, where the Achilles tendon attaches. It’s often called a “pump bump” because stiff-backed shoes, pumps, and skates rub against it and inflame the surrounding tissue. In my experience most cases settle with open-back or soft-back shoes, heel lifts, calf stretching, and calming the bursa — surgery to reshape the bone is reserved for heels that stay painful after a real trial of those steps.

What Haglund’s deformity actually is
Haglund’s deformity is an enlargement of the bone at the back of the heel, on the upper-outer corner of the heel bone (the calcaneus) where the Achilles tendon attaches. When that bony prominence rubs against the rigid back of a shoe, the skin and the small fluid-filled cushion behind the tendon (the retrocalcaneal bursa) get irritated — and that’s when a firm, tender, sometimes red bump shows up. The old nickname “pump bump” comes from the stiff-heeled pumps that classically trigger it, but I see it just as often from dress shoes, ski boots, ice skates, and stiff-backed work boots.
The bony bump itself is usually something you’re built with. What turns a harmless bump into a painful problem is the combination of that prominence, a tight Achilles, and a shoe that presses on it. Understanding that is the key to fixing it, because two of those three things are squarely within our control.
What it’s often confused with
Back-of-heel pain has a few overlapping causes, and they frequently travel together. When a patient comes in pointing at the back of the heel, I’m sorting between three things: Haglund’s deformity (the bony bump itself), retrocalcaneal bursitis (the inflamed cushion behind the tendon), and insertional Achilles tendinitis (irritation right where the tendon meets the bone). Many people have all three at once. That matters because the treatment overlaps but the surgical decision — if it ever comes to that — depends on which structures are involved.
Symptoms and warning signs
- A firm, bony bump on the back of the heel, often with redness or swelling over it
- Pain where the shoe’s heel counter presses — worst in stiff-backed shoes, better barefoot or in open-back shoes
- A blister, callus, or raw spot over the bump from rubbing
- Stiffness and pain at the back of the heel when you first get moving
- Tenderness just above the heel where the Achilles attaches
The giveaway I listen for is “my heel is fine in sneakers or sandals, but dress shoes and boots are agony.” That points straight at shoe pressure on the bump — and that’s very treatable.
What causes it
A few structural traits make Haglund’s more likely. A high arch tips the heel bone so the back corner sticks out more. A tight Achilles or calf increases the tendon’s pull and pressure on the bone. A naturally prominent heel-bone shape runs in families. And a tendency to walk on the outer edge of the foot concentrates load at the back of the heel. Layer rigid, tight-heeled shoes on top of any of those and the bump that never bothered you suddenly does.
Is mine serious? When to come in
Most Haglund’s pain is a pressure-and-irritation problem, not an emergency. But I want to see you if the pain has lasted more than a couple of weeks despite shoe changes, the skin over the bump is breaking down, the back of the heel is hot and very swollen, or you feel sudden weakness or a “pop” in the tendon — that last one needs prompt evaluation to rule out an Achilles problem. And if you have diabetes or neuropathy, please don’t tough out a raw spot on the back of the heel; reduced sensation turns rubs into wounds quickly.
What you can do right now
- Get the pressure off. Switch to open-back or soft-back shoes — clogs, mules, backless sneakers — so nothing rubs the bump. This single change relieves most people.
- Add a small heel lift. A 6–10 mm heel lift in both shoes reduces Achilles tension and lifts the bump above the shoe’s rub line. The most common mistake I see is people going barefoot to escape shoes, which actually stretches the irritated tendon more — a slight lift is usually better than flat.
- Stretch the calf and Achilles daily. Gentle calf stretches and, once the acute pain settles, eccentric heel drops reduce the tendon’s pull over time.
- Calm the inflammation. Ice the bump after activity and use an over-the-counter anti-inflammatory if it’s safe for you.
- Pad and protect. A silicone heel sleeve or felt pad shields the bump while the skin recovers.
One thing I steer patients away from: cortisone injections right into the back of the heel. So close to the Achilles, a steroid shot carries a real risk of weakening or rupturing the tendon, so it’s not something I reach for here. Give the conservative steps a genuine few weeks — the majority of heels quiet down without anything more.
What we actually do at your visit
I start by feeling exactly where the pain is — the bony corner, the bursa just in front of the tendon, or the tendon insertion itself — because that tells me which of the three overlapping problems is driving things. I check your calf flexibility and arch height, then usually take a weight-bearing X-ray to measure how prominent the heel bone is and look for any calcification in the tendon. If the bursa or tendon looks heavily involved, an ultrasound or MRI helps me see the soft tissue. From there we build a plan that almost always starts conservative.
When surgery is worth it
If the heel stays painful after a real trial of footwear changes, heel lifts, stretching, and physical therapy, surgery is reasonable. The core procedure removes or reshapes the bony prominence (a calcaneal osteotomy or resection); if the Achilles insertion is badly involved, part of the tendon may be cleaned up and reattached at the same time. Recovery depends on how much the tendon is involved — a simple bump resection lets you back into shoes relatively quickly, while a tendon repair means a boot and a more protected, longer rehab over a few months. I’ll walk you through exactly which version applies to your heel before we ever schedule anything.

Frequently asked questions
Can I get rid of a Haglund’s bump without surgery?
You can’t shrink the bone without surgery, but you can usually eliminate the pain. Open-back shoes, a small heel lift, calf stretching, and padding take the pressure off the bump, and most people become comfortable without an operation.
Why does the back of my heel only hurt in certain shoes?
Because the pain comes from the shoe’s rigid heel counter pressing on the bony bump. Stiff dress shoes, pumps, boots, and skates rub it; open-back or soft-back shoes don’t, which is why the same heel can feel fine in sandals and awful in heels.
Is a Haglund’s deformity the same as a heel spur?
No. A Haglund’s deformity is a bony bump at the back of the heel by the Achilles tendon. A classic heel spur sits on the bottom of the heel and is linked to plantar fasciitis. Different spot, different problem.
Can I prevent Haglund’s deformity from getting worse?
Yes. There’s a genetic predisposition you can’t change, but avoiding rigid-backed shoes, keeping the calf flexible, and using a heel lift when needed keep pressure off the bump and stop the cycle of irritation that makes it hurt.
