Corns and calluses are annoying and sometimes painful thickening in the skin in areas of repeated pressure from footwear. On the foot, calluses (hyperkeratosis) commonly occur on areas subjected to pressure and impact: the heels, balls of the foot, and the big toe. A callus is hard, dry, and thick, and it may appear grayish or yellow. It may feel bumpy and less sensitive to the touch than surrounding skin.
Corns generally occur on the tops and sides of the toes. A hard corn is a small patch of thickened, dead skin with a central core. A soft corn has a much thinner surface and usually occurs between the 4th and 5th toes. Although calluses and corns are not painful they may cause pain when walking and wearing shoes.
Calluses and corns are both caused by repeated pressure or frictions on an area of skin. The pressure causes the skin to die and form a hard protective surface. Calluses and corns are not caused by a virus and are not contagious. They can be treated with many types of medicated products to chemically pare down the thickened, dead skin.
Corns and calluses can be prevented by reducing or eliminating the circumstances that lead to increased pressure at specific points on the hands and feet. People with fragile skin or poor circulation in the feet (including many people with diabetes or peripheral arterial disease) should consult their health-care professional as soon as corns or calluses develop.
