The athlete's foot (tinea pedis) is a fungal infection that usually begins between the toes. It usually occurs in people whose feet become very sweaty while confined within tight shoes. Signs and symptoms of an athlete's foot include a scaly rash that usually causes itching, stinging, and burning. An athlete's foot is contagious and can be spread through contaminated floors, towels, or clothing. Athlete's foot is closely related to ringworm and other fungal infections such as ringworm. It can be treated with over-the-counter antifungal medications, but the infection often recurs.  Prescription drugs are also available. Athlete's foot usually causes a scaly red rash. The rash usually starts between the toes. Itching is often worst after you take off your shoes and socks. Some types of athlete's feet cause blisters or ulcers.  The moccasin variety of athlete's foot causes chronic dryness and scaling on the soles that extends to the side of the foot.  It can be mistaken for eczema or dry skin.
