Athlete's foot fungus may infect any part of the foot, but most often grows between the toes.The next most common area is the bottom of the foot. The same fungus may also affect the nails or the hands. Athlete's foot is not limited to just athletes: it can be caused by going barefoot in public showers, letting toenails grow too long, wearing shoes that are too tight, or not changing socks daily. #skincare #athletic #athletesfoot #feetnails #feetcare #feet
