Athlete’s foot is a common fungal infection that affects the skin on the feet, especially between the toes. It is caused by fungi that grow in warm, moist environments such as sweaty socks, tight shoes, or communal showers. The condition is contagious and can spread through direct contact or by walking barefoot on contaminated surfaces.

The infection often begins with mild itching or redness between the toes. As it progresses, the skin can become scaly, cracked, or peel away. In more severe cases, blisters may develop, and the area can feel sore or burn. The condition can also spread to the soles of the feet or toenails if not treated properly.

Athlete’s foot can affect anyone, but it is more common in people who wear closed shoes for long periods or who sweat excessively. Athletes, gym-goers, and those who frequently use communal showers are at higher risk. The infection can also recur easily if preventive steps are not maintained.
