Corns are one of foot's most common forms of reaction to abuse and stress.
These highly visible conditions signal that something is wrong and where. The corn is another attempt by the body to protect the foot. It is a small area of thick, dead layers of skin that serve as padding over skin tissue that is subject to excessive pressure. Excess pressure usually results from repeated wearing of tight, ill-fitting shoes. A contributing condition could be and underlying bone deformity that makes excess pressure more likely.
