The Nike Air Force 1 GTX Boot 'Black Gum' delivers a winter-ready version of the classic silhouette. A blacked-out finish is executed on the leather upper, secured with a silicone ankle strap and accented with a tonal Swoosh outlined in reflective detailing. Embroidered Gore-Tex branding on the lateral heel gives the nod to the sneaker's waterproof lining. The sneaker rides on a durable gum rubber cupsole, outfitted with large lugs for enhanced traction.
