The problem begins when bacteria are attracted to the sweat on your feet and start feeding on it. The bacteria’s excretion has a strong odor that causes your feet to smell bad. Since each foot has over 250,000 sweat glands in it, and produces over a pint of sweat a day, there’s a lot for the bacteria to eat. Shoes and socks even make the situation worse. They trap the sweat, and then the bacteria have their favorite kind of environment: dark and damp, causing them to go into a feeding frenzy.
