There are three types of athlete's foot that present differently: toe web infection between the toes causes scaly, peeled, cracked skin; moccasin type affects the heel and causes thick, cracked skin; vesicular type produces fluid-filled blisters under the foot. It spreads easily through direct contact or shared items and thrives in moist environments. While it can be treated with over-the-counter medications, prescription options or seeing a podiatrist may be necessary for severe cases. Proper foot hygiene and avoiding sharing items can help prevent repeat infections.
