Calluses are protective pads made up of the thickened upper layer of skin due to repeated rubbing of the area. Corns are small calluses that develop on the top of the toes due to pressure or rubbing against shoes or other toes.
Calluses are usually painless, but corns can be quite painful.
Sometimes corns are confused with warts. Calluses can be avoided by removing the source of the rubbing and thinning the callus with a pumice stone. Click here for a list of online resources .
