It’s safe to say that up and coming Nike designer Ben Kirschner killed it when he introduced the Nike SF-AF1 to the world. The polarizing militarized takedown of the Nike Air Force 1 kept the original outsole unit intact while the upper was completely overhauled with unique materials native to military boots to hold you down for the winter, but the creation was also head-turning enough to be one of the most sought after lifestyle creations of the Fall/Winter season. Now we get a look at an upcoming Nike SF-AF1 Grey colorway headed to retailers on February 17th in men’s sizes 8-13 only in rather limited quantities.Unlike past iterations of the Nike Special Field Air Force 1, this monochromatic grayscale update features a new pre-cracked leather throughout to additional vintage effect. The ballistic nylon retains its place on the heel and high-arching ankle collar while the coveted alternate paracord ankle strap will also be available for this coming release. What do you think of the Nike SF-AF1 Grey?
