Athlete's foot, known medically as tinea pedis, is a fungal infection of the skin of the feet. It is common and contagious, and it thrives in warm, damp places such as locker rooms, pool decks, showers and sweaty shoes.
Common signs
- Itching, burning or stinging, often between the toes
- Scaling, peeling or cracked skin
- Redness, or white soggy skin between the toes
- Dry, scaly skin on the soles and sides of the feet
- Small blisters in some cases
Different patterns
Athlete's foot can show up between the toes, as dry scaling over the sole and heel (sometimes called moccasin type), or as blisters. Because eczema, allergic reactions and psoriasis can look similar, a rash that does not respond to treatment should be examined.
Treatment
- Over-the-counter antifungal creams, sprays or powders, used as directed on the label, are often effective
- Continue treatment for the full recommended time, even after symptoms improve, because stopping early lets the infection return
- Keep the feet clean and dry while treating
- Prescription creams or tablets may be needed for stubborn or widespread infection
Prevention
- Dry your feet carefully, including between the toes
- Change socks daily, or more often if they get damp, and choose moisture-wicking fabrics
- Alternate shoes so they can dry out fully
- Wear sandals or shower shoes in public locker rooms and pool areas
- Do not share towels or shoes
- Treat fungal toenails, since they can keep re-infecting the skin
When to see a podiatrist
- No improvement after a couple of weeks of appropriate treatment
- The rash keeps returning
- Painful cracks, swelling, drainage, or redness spreading up the foot, which can mean a bacterial infection
- You have diabetes, poor circulation or a weakened immune system. People with these conditions should be seen early for any foot skin problem.
