Avoiding Corns, Calluses

If the shoe fits, wear it, and you probably won't develop a corn or callus. Corns and calluses can be caused by pressure from a shoe against the foot, according to the American Academy of Orthopaedic Surgeons. Corns and calluses most often develop on the big toe and fifth toe. Relieving the pressure on the foot is the best treatment for a corn or callus, and this is usually accomplished by changing the shoe.
