Athlete's foot (also known as tinea pedis) is the most common fungal infection of the skin. It thrives in warm damp places especially on calluses and between the toes. Symptoms include itching, cracking, burning and inflammation. The fungi spread quickly and easily when beneficial bacteria are destroyed by antibiotics or radiation. The fungus that causes athlete's foot can be found most often in wet damp places such as locker rooms.

Also a really bad name for a sports shoe store chain that I have seen located in central Florida.
