Pressure corns form when chronic pressure on the skin against an underlying bone traces a usually elliptical path during the rubbing motion. The corn forms at the center of the pressure point and gradually widens and deepens. Corns from an acute injury, such as a from a thorn in the sole of the foot, may form due to the weight of the body, when the process that creates the usually evenly developing plantar callus is concentrated at the point of the healing injury, as an internal callus may be triggered by pressure on the transitional scar tissue. A hard corn is called a heloma durum or clavus durus, while a soft corn is called a heloma molle or clavus mollis.

Many languages have metaphoric phrases for corns. Several are based on the word for ‘eye’: e. The hard part at the center of the corn resembles a barleycorn or shoe tack, that is, a cone or funnel shape with a broad top and a pointed tip at bottom. Because of their shape, corns intensify the pressure at the tip and can cause deep tissue damage and ulceration.
