Patients with diabetes are encouraged to pay special attention to their foot health. Neuropathy and poor circulation are two major concerns. Neuropathy can lead to loss of sensation, and the inability to feel heat, cold, or pain. Minor cuts or scrapes can cause serious infections. Poor circulation to the feet can cause those wounds to heal slowly and be more prone to infections and ulcers.

A callus is caused when there is an accumulation of dead skins cells that harden and thicken over an area of the foot. Calluses are most often formed in response to excessive pressure or friction, acting as protection for that area of the body. As it pertains to the foot, calluses are most often found on the main pressure points, including the ball of the foot, heel, and the inside of the big toe.
