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 growth that forms on or just beneath the bone. On the foot, it’s a relatively common orthopedic finding: many people first notice it as a palpable bump that rubs in the shoe or is visible from the outside. Not every bone spur causes pain—but if friction, pressure points, or inflammation develop, it’s worth getting it checked.

Important: A bone spur is not a cyst or a tumor, but actual bone tissue. This distinguishes it from so-called ganglia (ganglion cysts), which can also appear as lumps but are filled with joint fluid.

How does a bone spur develop?

There are many causes. Often, several factors interact:

Chronic mechanical stress When joints or bones are unevenly loaded over a long period, the body may respond by building additional bone. This particularly affects people who stand or walk a lot—or wear shoes that don’t suit their foot shape.

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

Inflammatory conditions Conditions such as osteoarthritis or rheumatoid arthritis can be associated with bony changes.

Injuries After fractures or chronic irritation, excess bone tissue can form.

Genetic predisposition In some cases there is a family 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 (heel spur) A heel spur is one of the best-known forms. It develops at the attachment of the plantar fascia or the Achilles tendon and can present as a sharp pain with the first steps in the morning—or remain completely symptom-free.

2. Top of the foot – dorsal exostosis Bony prominences can develop on the top of the foot that are especially noticeable due to lace pressure. High shoes or tight lacing can cause pressure points and local inflammation here.

3. Big toe – hallux valgus In hallux valgus, the big toe shifts outward, and a bony prominence forms at the base joint—the so-called “bunion.” Narrow toe boxes and limited toe room can promote this misalignment and worsen existing symptoms.

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

5. Between the toes – subungual exostosis Less common but possible: bone spurs can also develop 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, symptom severity, and cause. In general, there are conservative and surgical approaches—the decision always rests with the treating physician.

Conservative measures

Adjust your footwear: This is often the first and most effective step. A shoe that offers sufficient toe room, doesn’t constrict the top of the foot, and cups the heel well can significantly reduce pressure and friction.

Insoles: Orthopedic insoles can help relieve pressure points and correct faulty loading. They’re custom-fitted and can make an important contribution.

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

Anti-inflammatory measures: Cooling, anti-inflammatory creams, or—after consulting a doctor—medications can help during acute irritation.

Surgical treatment

If conservative measures don’t provide sufficient improvement over time, surgery may be considered. The bony growth is removed, and aftercare varies depending on the location and extent of the procedure.

What role does footwear play?

Ill-fitting footwear is rarely the sole cause of a bone spur—but it can significantly worsen existing symptoms. Key factors include:

• Adequate toe box: Toes should move freely without being squeezed.

• Proper width: Especially with existing misalignments like hallux valgus, sufficient shoe width is important.

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

• Stable yet lightweight sole: Good cushioning can absorb impact and ease joint stress.

At Giesswein, we rely on merino wool—a natural material that hugs the foot, is breathable, and can counteract pressure points. Combined with a thoughtfully designed sole, our footwear can help relieve and comfortably cradle your foot in everyday life—especially if you value comfort and a natural fit.
