Athlete’s foot

A common condition in which the skin between the toes becomes itchy and sore, and may crack, peel, or blister. It is due to a fungal infection but may also be caused by bacteria. Because the fungi thrive in humid conditions, athlete’s foot is more common in people with particularly sweaty feet and with shoes and socks made from synthetic fibres, which do not absorb sweat. Self-treatment with topical antifungal drugs is usually effective and should be combined with careful washing and drying of the feet.
