Prevent athlete's foot: regular cleaning of the feet & more
I would not like to say anything about the existing tips; the funds from the pharmacy are probably better.
I just want to point out that the regular cleaning of the feet, also between the toes, helps to protect against athlete's foot. If dirt, skin or sweat remains there, the skin stays moist longer and that's what the fungus likes. For washing in the indoor pool or sports club is also a shampoo. Those who have athlete's foot should wash their feet at home and then dry their toe gaps with a hair dryer. The fungus is sensitive to heat.
