Athlete’s Foot and fungal nails are extremely common – in fact the most common fungal problems with feet. A fungus is a common mold that thrives in dark, warm, and moist areas. On the feet, it can grow on and between toes, as well as on soles and toenails. The environment (socks, shoes, heat, humidity) may cause fungal problems as well as an unsteady immunity from disorders such as diabetes.
Intense fungal infections are more often seen in children, and chronic infections are most common in adults.
