Climbing shoes are notorious for retaining hard-to-remove foot odor, especially since they’re usually worn without socks that could help soak up any sweaty stink. To neutralize smells, you’ll need a powerful counteragent. Enter Extra Strength Lemon Eucalyptus Essential Oil Odor Eliminator ($15; lumioutdoors.com) from Utah-based Lumi Outdoors. This shoe spray relies on natural, antimicrobial ingredients for odor elimination, including essential oils of lemongrass, eucalyptus, tea tree, and peppermint. You’ll need to like the strong lemony, minty smell to use it (hint: apply it outdoors)—or at least prefer it to the eau de stankfoot you might otherwise emit.
