Bottom of foot callus

Calluses are a build-up of hard skin and are generally found beneath the weight bearing surfaces on the bottom of the foot. Some degree of callus formation on the sole of the foot of an active person is normal and generally does not cause any problems for a patient. Callus formation can also occur around the periphery of the heels, which can lead to fissuring of the callus, which can become quite painful. Some people use the terms "corns" and "calluses" interchangeably. Calluses are generally caused by an uneven distribution of weight, generally on the bottom of the forefoot or heel that leads to a build-up of hard skin. Calluses can be caused by wearing improperly fitted shoes and, in rare instances, an abnormality of the skin causing a build-up of callus tissue.

Calluses and corns are thickenings of the outer layer of skin. They develop to protect skin from damage against prolonged rubbing, pressure, and other forms of irritation. Calluses and corns usually form on the hands or feet. A callus is a thickening of skin exposed to prolonged rubbing.

Corns and calluses are thick, hardened layers of skin that develop when your skin tries to protect itself against friction and pressure. They most often develop on the feet and toes or hands and fingers. Corns and calluses can be unsightly. If you're healthy, you need treatment for corns and calluses only if they cause discomfort. For most people, simply eliminating the source of friction or pressure makes corns and calluses disappear.
