Understanding bone spurs on the foot – and discover comfortable Merino sneakers

What is a bone spur on the foot?

A bone spur—medically called an exostosis—is a benign bony outgrowth that forms on or just beneath the bone. On the foot it is among the more common orthopaedic findings: many people first notice it as a palpable bump that rubs in the shoe or shows visibly. Not every bone spur causes pain—but if friction, pressure points or inflammation occur, a thorough assessment is worthwhile.

Important: A bone spur is not a cyst or a tumour, but real bone tissue. This distinguishes it from so‑called ganglia, which can also appear as a lump but are filled with joint fluid.

How does a bone spur develop?

The causes are varied. Several factors often interact:

Chronic mechanical load When joints or bones are subjected to uneven load over a long time, the body may respond by building extra bone. This particularly affects people who stand or walk a lot—or wear shoes that do not suit their foot shape.

Misalignments Congenital or acquired foot deformities such as flat feet or fallen arches can alter pressure distribution and promote the development of exostoses.

Inflammatory conditions Disorders such as osteoarthritis or rheumatoid arthritis can be accompanied by bony changes.

Injuries Excess bone tissue can form after fractures or chronic irritation.

Genetic predisposition In some cases there is a familial tendency—if bone spurs run in your family, watch for early warning signs.

Where do bone spurs occur on the foot?

There are several typical sites on the foot where exostoses can occur. The most common at a glance:

1. Heel bone – calcaneal spur The heel spur is one of the best‑known forms. It develops at the insertion of the plantar fascia or the Achilles tendon and may present as a sharp pain on first stepping in the morning—or remain completely symptom‑free.

2. Dorsum of the foot – dorsal exostosis Bony prominences can form on the top of the foot, often noticeable because of instep pressure from the shoe. High vamps or tight lacing can cause pressure points and local inflammation here.

3. Big toe – hallux valgus With hallux valgus the big toe drifts outward, and a bony prominence forms at the base joint—the so‑called bunion. Narrow toe boxes and limited toe room can encourage this deformity and aggravate existing symptoms.

4. Little toe – tailor’s bunion (bunionette) Similar to hallux valgus but at the little toe: a growth forms on the outer edge of the foot, which can be particularly troublesome in narrow footwear.

5. Between the toes – subungual exostosis Less common but possible: bone spurs can also form under the toenail or in the toe area—often after injuries.

Treatment: What helps with a bone spur on the foot?

Treatment depends on the location, the severity of symptoms and the cause. In principle, one distinguishes between conservative and surgical approaches—the decision always rests with the treating doctor.

Conservative measures

Adjust your shoe choice: This is often the first and most effective step. A shoe that offers sufficient toe room, does not constrict the instep and beds the heel well can significantly reduce pressure and friction.

Insoles: Orthopaedic insoles can help offload pressure points and balance malloading. They are individually fitted and can make an important contribution.

Physiotherapy: Targeted exercises can strengthen the surrounding muscles and reduce load on affected areas.

Anti‑inflammatory measures: Cooling, anti‑inflammatory ointments or—after consulting a doctor—medication can be helpful during acute irritation.

Surgical treatment

If conservative measures do not provide sufficient improvement over a longer period, surgery may be considered. The bony outgrowth is removed. Aftercare varies depending on the location and extent of the procedure.

What role does footwear play?

Poorly fitting footwear is rarely the sole cause of a bone spur—but it can significantly worsen existing symptoms. The key factors are:

• Sufficient toe box: Your toes should be able to move freely without being squeezed.

• Appropriate width: Adequate shoe width is important, especially with existing deformities such as hallux valgus.

• Breathable material: Materials that adapt to the foot’s shape and ventilate well can reduce friction and pressure points.

• Stable yet light sole: Good cushioning can absorb impact and relieve the joints.

At Giesswein we rely on merino wool—a natural material that conforms to the foot, is breathable and can counteract pressure points. Combined with a well‑designed sole structure, our footwear can help relieve the foot and provide comfortable support in everyday life—especially if you value comfort and a natural fit.
