Nike presents the perfect SF-AF1 boot for the up and coming winter season. This time around we see the sneaker dawned in three colors, each showcasing tumbled leather and ballistic canvas uppers. What sets these boots apart from the original SF-AF1 is the zipper lace, coupled with thick rope style laces and lace lock tying up the ankle. Each features a 3M 'AIR' accent running up the lateral side of each boot. Each variation is also off set with a different colored out sole for a nice cut of contrast. Purchase your favorite of the three online and in-store.
