We specifically formulated Dr. Scholl’s® Odor-X Antifungal Spray Powder for people who are concerned about annoying foot odor, athlete’s foot or both. When moisture is trapped in your shoes, it creates an environment where athlete’s foot fungus on your feet can thrive and odor can develop. Dr. Scholl’s® Odor-X® Antifungal Spray Powder controls wetness to help prevent odor, and uses Tinactin® Antifungal to prevent most athlete’s foot.
