This edition of the SF Air Force 1 High Ibex Men's Boot takes the concept of urban utility to new heights. It's built with a quick-cinch closure system and easy-to-clean Ibex leather, so your whites stay white all winter long. VERSATILITY Rope laces, lace loops and a metal lace lock work together as a dynamic closure system. This gives you a variety of ways to wear and secure your shoe. DURABLE MATERIALS The heel, collar 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. The synthetic leather is designed to wipe clean with a simple swipe.
