What is Athlete’s Foot Fungus?
Athlete’s foot fungus, also known as tinea pedis, is a common fungal infection that affects the feet. It is caused by a type of fungi called dermatophytes, which thrive in warm, moist environments. The fungus feeds on keratin, a protein found in skin, hair, and nails, and can cause a range of symptoms including itching, burning, and cracking of the skin.
If left untreated, athlete’s foot fungus can spread to other parts of the body, including the toenails, hands, and groin area. It can also lead to more serious complications, such as bacterial infections and chronic fungal infections. Fortunately, athlete’s foot fungus is relatively easy to treat with antifungal medications and good foot hygiene practices.
How does Athlete’s Foot Fungus Spread in Shoes?
Athlete’s foot fungus can spread in shoes through contact with infected skin cells, sweat, and fungal spores. When an infected person wears shoes, the fungus can thrive in the warm, moist environment inside the shoe.
