Apply a foot cream like Kiehl's Cross-Terrain Dry Run ($18) to help moisturize skin while absorbing excess sweat. You can use regular body lotion, too, but most foot creams have specific ingredients to soften calluses and contain antifungal components to prevent fungus growth and stench. Dry your feet completely before putting on socks and shoes.
