Hard skin / Callus / Hyperkeratosis
Callus forms on areas of high pressure and friction. It is not a bad thing to have, as it demonstrates that you have good circulation and that you are active.
Managing your callus is something that, as a podiatrist, I can help you with, but likewise I can teach you how best to manage your own callus.
Hard skin may build up over a small or a large area on the foot.
This can be due to the way your foot functions, how your skin functions or how your foot is shaped.
