Athlete's foot is caused by fungus. Fungus thrives in warm, dark, moist places such as the inside of a shoe, locker rooms, showers, and swimming pool areas. The fungus can exist on a floor, mat, rug, shoe, or towel and transfer to your skin when your feet come in contact with them. You can also get athlete's foot if you come into contact with fungus on someone else's feet. The fungus can then grow on your skin if your feet or the area between your toes stays slightly wet.
