Thick, hard callused skin can form on areas of your feet where there has been repeated high pressure over a period of time, or shearing stress and friction, such as shoes rubbing.


  1. Increased pressure causes the cells to reproduce more quickly and the protein in the cells is turned into keratin at a faster rate than usual.
  2. These cells are less easily shed from the surface of the skin because they are harder and more compacted and so layers of thickened skin builds on areas that are exposed to abnormal pressure or frictional forces.

This build up of hard skin is a protective mechanism; it is your body’s way of creating an added layer of protection to protect the tissues underneath.

If the pressure and rubbing continues hard, callused skin can form which can be uncomfortable. Read more about how to treat callus here and don’t forget you can use our forum if you have any foot questions!
