A hammertoe can rub against the shoe and create a painful focused corn.

Corns & calluses treatment
Corns and calluses are protective skin responses to repeated pressure or friction. Lasting relief depends on identifying why the pressure keeps returning—not only trimming the thickened skin.
Pressure leaves a pattern
A corn is often a smaller, focused area with a hard center on or between the toes. A callus is usually broader and forms beneath the foot or over another repeated pressure point.
A hammertoe can rub against the shoe and create a painful focused corn.
Moisture and pressure between adjacent toes may produce a softer corn.
A broad callus may reflect repeated loading under a metatarsal head.
Shoe friction over a bony area can thicken the skin and create tenderness.
Treat the cause, not only the skin
The examination may assess the skin pattern, foot shape, toe alignment, joint motion, walking pressure, footwear, sensation, and circulation. The goal is also to distinguish corns and calluses from warts or another skin lesion.
Confirm whether the area is a corn, callus, wart, or another skin problem.
Look for shoe friction, hammertoe, bunion, prominent bone, or altered loading.
Review diabetes, circulation, sensation, wounds, and prior infection before treatment.
Relief plus prevention
Do not shave or cut corns and calluses at home. Medicated acid pads can damage surrounding skin and are especially unsafe with diabetes, neuropathy, or poor circulation.
Protect the skin barrier
Arrange prompt evaluation when thickened skin becomes warm, swollen, red, draining, cracked, or ulcerated, or when pain is increasing. People with diabetes, reduced sensation, poor circulation, or immune suppression should not attempt self-treatment.
A callus can hide a pressure injury beneath the surface. Skin that looks “only thick” may need closer inspection when sensation is reduced.
