Nike's latest interpretation of the classic Air Force 1 silhouette might be the best one yet! The SF-AF1 Mid updates the Air Force 1 with a military-inspired design. A ballistic nylon upper protects you from all the elements and removable ankle strap allows for a custom look. Standard laces; an ankle strap and a dual-zipper heel work together as a dynamic closure system. This gives you a variety of ways to wear and secure your shoe. Heel and tongue are made with a ballistic nylon material. This makes the shoe durable and flexible and gives it a look inspired by military field boots. Premium leather forefoot and overlays. Foam midsole with Nike Air cushioning for comfort. Rubber outsole for traction and durability.
