The Nike SF Air Force 1 Mid in youth sizing is a military-inspired boot built for urban exploration. Based off the classic Air Force 1 Mid silhouette, the utilitarian SF — short for "special field" — AF1 features a Desert Moss suede toe, mid-panel, and eyelets with green ballistic mesh covering the lateral panel as well as the tongue. Branding unique to the Air Force 1 SF appears above the midsole on the lateral panel. A key design element exclusive to this model is a heel-based quick-cinch closure system that makes taking the shoes on and off easy. A sturdy green nylon strap with an adjustable notch allows for a lockdown fit. Completing the look of this mid-top silhouette is a thick gum rubber sole designed to withstand harsh conditions.
