CORN AND CALLOSITIES
Corn consists of a localised thickening of the skin cornea, which forms a core in the shape of a cone, and is often painful. They can be found on the articulations of hammertoes (hard corn), between the toes (soft corn), or on the foot sole.
Callosities are a diffuse thickening of the skin of variable sizes, typically observed under the foot’s forepart or the heel.
Both these foot issues are often caused by shoes that are not adjusted adequately; they can also be the result of a mechanical instability of the foot that creates a friction or a repeated overload of pressure on the affected area. Dry skin is also a common initial factor.
