Athlete's foot is an infection of the feet caused by fungus. The medical term is tinea pedis. Athlete's foot may last for a short or long time and may come back after treatment.
These tips can help you avoid athlete's foot or ease the symptoms if infection occurs:
* Keep your feet dry, especially between your toes. Go barefoot to let your feet air out as much as possible when you're home.
* Go with natural materials. Wear socks that are made of natural material, such as cotton or wool, or a synthetic fiber designed to draw moisture away from your feet.
* Change socks and stockings regularly. If your feet sweat a lot, change your socks twice a day.
* Wear light, well-ventilated shoes. Avoid shoes made of synthetic material, such as vinyl or rubber.
* Alternate pairs of shoes. Don't wear the same pair every day so that you give your shoes time to dry between wearings.
* Protect your feet in public places. Wear waterproof sandals or shower shoes in communal showers, pools, fitness centers and other public areas.
* Treat your feet. Use powder, preferably antifungal, on your feet daily.
* Don't share shoes. Sharing risks spreading a fungal infection.

Try to keep your feet dry. The fungus that is living off of your foot needs moisture to survive. So... after you shower, make sure that you've wiped off all the excess water. You should also try to avoid wearing your shoes and socks for too long.

It's probably caused by unclean feet. To relieve, there are lotions that you can find at the local drugstore.
