Athlete's foot, also called tinea pedis, is a fungal infection of the foot. It causes peeling, redness, itching, burning, and sometimes blisters and sores.
Athlete's foot is a very common infection. The fungus grows best in a warm, moist environment such as shoes, socks, swimming pools, locker rooms, and the floors of public showers. It is most common in the summer and in warm, humid climates. It occurs more often in people who wear tight shoes and who use community baths and pools.
