Apply an antifungal foot powder to the affected area to help protect your feet and reduce the friction between the foot and sock. Avoid nylon socks and plastic shoes and if possible wear open shoes made of leather or canvas, give your feet a chance to breathe whenever possible.
Never share socks, shoes or towels. If you have athletes foot always wash towels in the hottest water possible.
When using communal swimming/showers areas wear waterproof shoes or flip flops and avoid walking around barefoot. Make sure if you have pedicures that the instruments used are cleaned thoroughly.

It is quite common to spread to the groin area as it can be transferred with towels or on your hands. When touching the infected area always wash your hands thoroughly after.
In severe cases, damaged skin can become infected by bacteria leading to cellulitis, an infection of the deep layers of skin. If you suspect cellulitis you should contact your doctor straight away for treatment.
