Athlete’s foot is an itchy skin infection on the foot caused by contact with fungus. Prevention is the best cure for athlete’s foot. Steer clear of walking barefoot in places like public pools and showers, foot baths, water-parks, and changing rooms. It also helps to wear open-toe shoes, sandals, or sweat-wicking socks, and to sanitize your shoes daily. This all sounds straightforward, but there is a lot of misinformation about athlete’s foot out there.
