Nike has just given us a peek at the Air Max BW Spring 2014 pack due out in the first quarter of next year. The Big Window FB silhouette features the iconic extra large visible air unit in the heel and comes in its original black/persian violet/white sail colorway. Also included in the pack is the BW Generation II model, updated with Nike Hyperfuse and Free technologies making the shoe lighter and more comfortable than the OG version. It comes in the same black/persian violet/white sail colorway as well as a black/light crimson/white iteration. Although adjustments are minor, the Gen II undoubtedly sports a fresher, modern feel. We’ll keep you in the loop when the Spring 2014 pack is expected to drop.
