Corns and calluses are hard, thickened areas of skin that form as a consequence of rubbing, friction or pressure on the skin
They form on the feet and can make walking painful.
Corns generally occur on the tops and sides of the toes. A hard corn is a small patch of thickened, dead skin with a small plug of skin in the centre. A soft corn has a much thinner surface, appears whitish and rubbery, and usually occurs between the toes.
Causes, incidence, and risk factors:
Some corns and calluses on the feet develop from an improper walking motion, but most are caused by ill-fitting shoes. High-heeled shoes are the worst offenders. They put pressure on the toes and make women four times as likely as men to have foot problems. Other risk factors for developing a corn or callus include foot deformities and wearing shoes or sandals without socks, which leads to friction on the feet.
Rubbing or pressure can cause either soft corns or plantar calluses
