John Chisholm, DPM is a podiatrist in Chula Vista, California, and president of the California Podiatric Medical Association. Chisholm, like most foot doctors, is a big fan of socks. He says that socks serve two important functions: they reduce friction between the shoe and the skin, which prevents blisters and abrasions; and they provide a physical barrier between the foot and the microbial petri dish that is a sweaty shoe.

"If you were to take a scraping off a well-worn leather shoe, you'd find it's a zoo of micro-organisms that can cause disease in the human foot," says Chisholm, noting that the number one threat is the athlete's foot fungus. "It likes places that are dark, warm, and don't have a lot of air circulation, like the inside of a shoe." Chisholm notes that the athlete's foot fungus is not only the cause of the classic raw, scaly patches between toes, but also most toenail fungal outbreaks.
