Haglund's Deformity
Symptoms & Treatment

Overview

Haglund's deformity is a bony prominence on the back of the heel bone, also called the calcaneus. It sits near the Achilles tendon attachment and can become painful when the back of a shoe rubs against it.

The condition is often called a pump bump because rigid-backed shoes, including pumps and dress shoes, can press directly against the enlarged area. The same irritation can happen with skates, work boots, cleats, hiking shoes, or any shoe with a stiff heel counter.

The bump may be present for a long time before it hurts. Symptoms often begin when shoe pressure, activity, tight calf muscles, high arches, or Achilles tension cause inflammation around the heel.

What Is Haglund's Deformity?

Haglund's deformity is not just a soft lump. It is an enlargement of bone at the back of the heel. The soft tissue around the Achilles tendon can become irritated when this bony prominence rubs against shoes.

That irritation can inflame the retrocalcaneal bursa, a small fluid-filled cushion between the heel bone and Achilles tendon. It can also aggravate the Achilles tendon insertion, especially when the tendon is tight or already irritated.

Because the problem sits where the Achilles tendon, heel bone, shoe pressure, and bursa all meet, symptoms can feel like a mix of heel spur pain, Achilles tendonitis, bursitis, and shoe-rub irritation.

Is Haglund's Deformity The Same As A Heel Spur?

No. The terms overlap in casual conversation, but they are not the same target.

Heel spurs can describe different bony projections from the heel bone, including spurs under the heel near the plantar fascia and posterior spurs near the Achilles tendon. Haglund's deformity is specifically the enlarged bump on the back of the heel where the Achilles area is exposed to shoe pressure.

That distinction matters because treatment needs to address the exact pain generator: the bony prominence, shoe friction, bursitis, Achilles irritation, foot structure, gait mechanics, or a combination of those factors.

What Causes Haglund's Deformity?

There is not always one clear cause. Many patients have a heel shape or foot structure that makes the back of the heel more likely to rub against shoes. Symptoms often appear when that structure meets friction, pressure, overuse, or tight soft tissue.

Common contributors include:

• Inherited heel shape or family tendency toward posterior heel prominence.
• High arches that change the angle of the heel and increase pressure near the Achilles insertion.
• Tight Achilles tendon or calf muscles.
• Rigid-backed shoes, pumps, dress shoes, skates, work boots, or tight heel counters.
• Running, hill training, jumping, skating, court sports, or repetitive heel stress.
• Walking mechanics that increase pressure on the outside or back of the heel.
• Recent training increases, weight changes, or new footwear.
• Existing Achilles tendon irritation or heel bursitis.

Who Is More Likely To Develop Symptoms?

Anyone can develop Haglund's deformity symptoms, but some people are more prone to irritation because of foot shape, shoe habits, or activity demands.

• People with high arches or a prominent back of the heel.
• People with tight calves or tight Achilles tendons.
• Runners, walkers, skaters, dancers, and athletes who repeatedly load the heel.
• People who wear rigid dress shoes, pumps, boots, cleats, or skates.
• People with recurring heel pain, Achilles pain, or shoe-rub blisters.
• People whose job requires long standing, walking, stairs, ladders, or hard-surface work.
• Patients with foot alignment issues or broader foot deformities that change heel pressure.

Common Symptoms Of Haglund's Deformity

Symptoms can range from mild irritation in one pair of shoes to daily pain that limits walking, exercise, and footwear choices.

• A visible or palpable bump on the back of the heel.
• Pain where the Achilles tendon attaches to the heel.
• Swelling around the back of the heel.
• Redness, warmth, or tenderness near the bump.
• Blisters, calluses, or skin irritation from shoe rubbing.
• Pain that worsens in shoes with rigid backs.
• Pain with uphill walking, stairs, running, jumping, or pushing off.
• Morning stiffness or tightness through the Achilles area.
• Difficulty wearing dress shoes, work shoes, skates, boots, or athletic shoes.

How Haglund's Deformity Irritates The Bursa And Achilles Tendon

The bony bump can compress soft tissue between the shoe and heel. Over time, that pressure may inflame the bursa near the Achilles tendon, creating painful swelling at the back of the heel.

The Achilles tendon can also become irritated where it attaches to the heel. This can make the area painful with walking, running, stairs, hills, and any activity that loads the calf and Achilles system.

When bursitis and Achilles irritation are both present, treatment has to reduce pressure and calm inflammation while also improving tendon flexibility, shoe fit, and foot mechanics.

How A Podiatrist Diagnoses Haglund's Deformity

Diagnosis starts with a careful history: where the pain is located, which shoes make it worse, whether the bump has grown, what activities trigger symptoms, and whether there is Achilles pain, swelling, redness, or blistering.

A foot and ankle exam may include checking the heel bump, Achilles insertion, bursa tenderness, skin irritation, shoe pressure points, calf tightness, arch height, gait mechanics, ankle range of motion, and related heel or tendon conditions.

X-rays are often used to evaluate the shape of the heel bone and the size and position of the bony prominence. Ultrasound or MRI may be considered when the bursa, Achilles tendon, or surgical planning needs more detail.

What You Can Try Before Your Appointment

Early symptom control focuses on reducing pressure and inflammation. These steps may help calm irritation while you arrange evaluation:

• Switch away from shoes with rigid backs or tight heel counters.
• Choose open-back shoes temporarily if safe for your activity and environment.
• Use padding to reduce friction over the heel bump.
• Use ice wrapped in a thin cloth for short periods after activity.
• Reduce hills, running, jumping, skating, or activities that worsen pain.
• Avoid aggressive stretching if it sharply increases Achilles pain.
• Follow medication directions carefully and ask a clinician if anti-inflammatory medication is safe for you.

Home care does not remove the bony prominence. It may reduce pain and swelling, but recurring symptoms need a proper diagnosis and plan.

What Not To Do With A Painful Heel Bump

Small changes can help, but the wrong approach can keep the area inflamed.

• Do not keep forcing the heel into shoes that rub the bump.
• Do not ignore redness, swelling, drainage, open skin, or worsening pain.
• Do not assume every back-of-heel problem is just a shoe blister.
• Do not push through Achilles pain during running, jumping, or hill work.
• Do not cut holes in work shoes or modify protective footwear in a way that creates safety risks.
• Do not self-inject or seek steroid injections around the Achilles without careful medical guidance.

Treatment Options For Haglund's Deformity

Treatment is usually aimed at reducing symptoms, inflammation, and pressure. The bony enlargement generally does not shrink with nonsurgical care, but many patients improve when the irritation around it is controlled.

Shoe changes and pressure relief

Changing shoes is often the first major step. Shoes with softer heel counters, better heel room, or an open back can reduce direct friction. Padding, heel lifts, or heel cups may help reduce pressure and tension at the back of the heel.

Orthotics and mechanics

Over-the-counter or custom orthotics may help when arch shape, heel position, gait mechanics, or pressure patterns contribute to repeated irritation. Orthotics do not erase the bump, but they can improve how force moves through the foot.

Inflammation control

Ice, activity modification, anti-inflammatory measures, and temporary reduction of irritating activities may help calm bursitis and soft-tissue swelling. Some patients may need short-term immobilization when pain is severe.

Physical therapy and stretching

Physical therapy may focus on calf flexibility, Achilles loading tolerance, ankle mobility, gait mechanics, strengthening, and reducing repeated compression at the back of the heel. Stretching has to be matched to the patient because aggressive tension can worsen symptoms in some Achilles insertion problems.

Surgery when conservative care fails

Surgery may be considered when pain, bursitis, Achilles irritation, or shoe intolerance persists after structured nonsurgical care. Surgical treatment may remove the painful bony prominence, remove inflamed tissue, smooth the heel contour, and address diseased Achilles tendon tissue when needed.

Surgery, Recovery, And Return To Activity

Surgery is not the first step for most patients. It is usually reserved for symptoms that remain limiting despite shoe changes, padding, orthotics, therapy, activity modification, and inflammation control.

Recovery depends on the procedure performed and whether the Achilles tendon needs to be detached, repaired, or protected. Some patients recover over several weeks to a few months, while more involved Achilles procedures can require a longer staged recovery.

Postoperative care may include swelling control, wound care, a boot or cast, protected weight bearing, gradual return to shoes, physical therapy, strengthening, and a progressive return to activity.

How To Help Prevent Haglund's Deformity Pain

You may not be able to change inherited heel shape, but you can often reduce the irritation that makes Haglund's deformity painful.

• Avoid shoes with hard backs that press directly on the bump.
• Choose footwear with enough heel depth and a softer heel counter.
• Use padding or heel lifts when appropriate to reduce friction.
• Replace shoes that create repeated rubbing or blistering.
• Increase running, hill work, skating, and jumping gradually.
• Address tight calves, Achilles stiffness, high arches, and gait mechanics.
• Use orthotics when foot structure or pressure patterns contribute to symptoms.
• Schedule care early when posterior heel pain keeps coming back.

When A Back-Of-Heel Bump Needs Prompt Attention

Schedule care if you notice:

• A painful bump on the back of the heel.
• Swelling, redness, warmth, or tenderness around the Achilles area.
• Blisters, calluses, drainage, or open skin from shoe rubbing.
• Pain that keeps returning whenever you wear regular shoes.
• Pain that limits walking, work, running, sports, or stairs.
• Achilles tendon pain, weakness, or trouble pushing off.
• Symptoms that do not improve after changing shoes and reducing friction.
• Diabetes, neuropathy, poor circulation, immune problems, or a history of foot wounds.
