“How can I prevent and treat athlete's foot?”

Athlete's foot usually occurs due to moisture. The drier you keep your feet, the better control you will have. I recommend you be evaluated by a foot and ankle specialist (podiatrist) for diagnosis, and treatment options,

For the straight forward approach, make sure your socks are clean (dont double wear or wear same pair for prolonged periods of time!) , wear breathable shoes- meaning, make sure they arent tight, unless youre actively running, make sure shoelaces allow for breathability and the size is not one that is tight around your ankle or ball of your foot. Use drying powder or antifungal powders or sprays in your shoes. Spray as often as you need based upon your feet sweating or activity. When able wash your feet with soap and water twice daily and pat dry, including between the toes. I also recommend a fresh pair of socks for bed time and lathering your feet with lotrimin or another antifungal cream before putting the socks on for the overnight. If you have many calluses, you may need to do some form of calluse removal prior to initiating overnight creams for them to be effective. Dr Garcia
