Favourable conditions for athlete’s foot include:
- Continually sweaty feet
- Wet socks
- Shoes that are too tight and cause friction
- A bandage that remains on foot long enough to soften skin
- Infection mostly occurs between toes or on soles or sides of feet. At first, skin becomes white and soft, then it cracks and peels. It is usually (although not always) itchy. When the top layer is removed, the skin below is red. Occasionally blisters develop, which can be very painful, especially if they are on the bottom of the feet. When toenails are infected, they may become thick, yellow and crumbly.
