Q. A 28-year-old marathon runner presents with a two-week history of itching, scaling, and redness between the toes of both feet. The patient reports that the symptoms began shortly after starting training in a communal gym. They have tried over-the-counter moisturizers without relief. The patient has no significant past medical history. On physical examination, there is erythema, scaling, and maceration between the toes, particularly in the web spaces. The soles and dorsal aspects of the feet are not affected. What is the most appropriate initial management for this patient?
