In between acrimonious Tweets from Tyler the Creator to Bruno Mars and appearance of Lady Gaga as alter ego Jo Calderone, last night's MTV VMAs filled the air wave with stunning surprises, like the supposedly impromptu "Otis" performance from Jay-Z and Kanye West. But seasoned Kanye watchers knew something else - the performance might yield a glimpse at the yet-to-be-official Nike Air Yeezy 2. From its first appearance on Black Mamba film set with Kobe Bryant and a semi-official viewing on the stage of Coachella music festival, fans already seen plenty of the black variant of Air Yeezy 2. Last evening's festivities were quite different, however. It marked the debut of the design's Zen Grey colorway, making it 2 of 3 colorways based on the original Air Yeezy.
