why do my feet smell?

your feet have small sweat glands that secret fluid. this fluid has various enzymes, protiens and electrolytes in it's composition. sweat starts out sterile. once it hits the enviroment, it collects bacteria, mold, fungus and viruses. these are what cause your feet to smell. the rule of thumb for anytype of bacterial growth is "a warm dark moist enviroment will encourage growth and overgrowth of skin flora". try changing socks frequently and going bare footed whenever you can and it's appropriate.
