What are Corns and Calluses?


Corns and calluses are thickened areas of skin that develop in response to repeated pressure, friction, or irritation.

Corns are small, round areas of thickened skin that typically develop on the tops and sides of the toes or between the toes.  They may be hard and dry (hard corns) or soft and moist (soft corns).  Hard corns often have a dense core, while soft corns are more rubbery and may appear white and mushy.

Calluses are larger, flat areas of thickened skin that usually form on the soles of the feet, especially on weight-bearing areas like the heels or balls of the feet.  They are typically yellowish or grayish in color and may feel less sensitive to touch compared to surrounding skin.


Corns and calluses develop as a protective response to repeated friction, pressure, or irritation on the skin.  Common causes include wearing tight or ill-fitting shoes, high heels or shoes with narrow toe boxes, walking barefoot, participating in activities that involve repetitive movements or pressure on the feet and foot deformities such as bunions or hammertoes.

While corns and calluses are generally harmless, they can cause discomfort and may increase the risk of developing other foot problems, such as blisters, infections, or ulcers, especially in individuals with diabetes or compromised circulation.
