Calluses and corns are areas of thick, hard skin that form on your foot due to pressure on your foot. Calluses are normal and typically do not have to be treated unless they cause you pain. You should never cut off calluses on your own. This can cause an infection and can be extremely dangerous if you have diabetes. One home treatment is to soak your feet in warm water and then wear away the dead skin with a pumice stone. You can also use orthotic inserts, and wear better-fitting shoes to reduce the pressure on your feet, lessening the development of calluses.
