The foot is dry and cracked, also known as foot fissures, foot chaps are commonly found in the plantar, toe or heel areas of the foot. It is often caused by inflammation of the skin of the foot, thickening of the stratum corneum or dry skin, which reduces the elasticity and increases the brittleness of the skin, and then the external forces pulling on it (e.g. walking, etc.) lead to dry and cracked skin.
