Corns and calluses are caused by underlying bone problems that cause excessive irritation. Where shoes repeatedly rub, dead skin cells pile up, creating calluses on the bottom of the foot and corns on the toes. The American Podiatric Association warns that you should never attempt to cut or dissolve corns or calluses at home. Your podiatrist can trim or protect them if they become painful, but they usually grow back unless the underlying problem is corrected surgically. Foot odor results from excessive perspiration from the more than 250,000 sweat glands in the foot.
Daily hygiene is essential to keep feet clean.
Air out shoes daily to evaporate moisture, and change your socks a couple of times a day. Foot powders, antiperspirants, and soaking in vinegar and water can help lessen odor too. Hammertoes buckle into a claw-like position and corns form at the bent joint when these toes rub against the tops of shoes. Usually, the second toe bends into this unnatural shape, but any of the other three smaller toes can be affected as well. Square, open-toed, or prescription shoes may increase comfort.
