Corns: These are small circles of hardened skin. They commonly occur over the
toes and soles of the feet. Usually associated with poorly fitting footwear or
deformed toes/joints. However, corns can appear anywhere.
Callus: These are hard, rough areas of skin that are often yellow in colour. They
are usually seen on the foot around the heels, balls of feet or tips of your toes.
Any form of friction or pressure against the foot e.g. from the ground, shoe or
even bone can result in the formation of callus. It is deemed to be protective
tissue, however, if not kept to a reasonable thickness can become painful.
