Athlete's Foot can be an irritating condition to deal with.  It's cause by a fungal infection that loves warm, dark, moist places and one of the best places for a fungal infection to find such a place is between the toes of your feet.

Males are often afflicted with this condition because they have sweaty feet and often have their feet covered and stuck in socks for the majority of the day.

There are many anti-fungal treatments available.  The most natural thing to do, is give your feet some fresh air at night.  Don't use the same shoes every day, wash your feet every day and don't share your shoes and socks with others.
