What is Athlete's Foot?
Athlete's foot is a common fungal infection affecting the skin of the feet, particularly between the toes, causing itching, redness, flaking, and sometimes cracked or sore skin. It thrives in warm, moist environments, such as inside shoes and socks, and spreads easily in communal areas like swimming pools, gyms, and changing rooms.
