Athlete's foot, known medically as tinea pedis (TIHN-ee-uh PEHD-ihs), is a fungal infection of the feet. Common symptoms include peeling, cracking, or scaling skin between the toes, especially the fourth and fifth toes. The skin may also itch and blisters or scaling may appear on the soles or sides of the feet. The fungus that causes athlete's foot is somewhat contagious and may be picked up from damp floors, shared towels, or infected persons. However, it requires a warm, moist environment to thrive, so just touching the fungus won't necessarily cause athlete's foot. In addition, some individuals seem more prone to the problem than others, though doctors aren't sure why. The best way to prevent athlete's foot is to keep the feet clean, dry, and well ventilated. Wear sandals when weather allows and cotton socks at other times. Wash your feet daily and dry them well, especially between the toes. Use foot powder during the summer. Anytime your feet become damp, change into dry shoes and socks. If you suspect you may have athlete's foot, treat it promptly. Untreated infections can spread to the toenails, where they become extremely difficult to resolve. When confined to the foot, the problem can usually be cleared up with drying foot soaks and anti-fungal creams or pills.
