Calluses are areas of thick, hardened, dead skin. They form to protect the skin and body structure under the skin from pressure, friction, and injury. They may look grayish or yellowish, be less sensitive to the touch than surrounding skin, and feel bumpy.

Calluses on the feet generally form on the ball of the foot, the heel, and the underside of the big toe. They often form where the foot and the beginning of the toe meet (under the end of the metatarsal bone).
