The best way to get rid of athlete's foot as soon as possible is to practice good hygiene and take preventive measures to avoid reinfection. To start, make sure to keep your feet clean and dry. Wash your feet daily with soap and warm water, and dry them thoroughly, especially between the toes. Wear socks made of natural fibers that wick away moisture and change your socks at least once a day. Also, wear shoes or sandals that allow your feet to breathe, and rotate between a few pairs so that they can air out.
In addition, you should avoid walking around barefoot in public places, such as locker rooms, public showers, and pools, as these are common breeding grounds for the fungus that causes athlete's foot. If you must walk around barefoot, wear flip flops or sandals.
If you already have athlete's foot, you can use an over-the-counter anti-fungal cream, lotion, powder, or spray. Follow the instructions on the product label, and be sure to apply the cream or powder between your toes. You may also need to use an anti-fungal powder or spray in your shoes. If your symptoms do not improve after a few weeks, contact your doctor for a prescription anti-fungal medication.
Finally, make sure to take extra precautions to avoid reinfection. Wash and dry your feet thoroughly each day, and change your socks often. Wear clean socks and shoes each day. Avoid sharing towels or shoes with others, and wear sandals or flip flops in public places, such as locker rooms and showers. With these preventive measures, your athlete's foot should clear up quickly.
