Nike officially unveiled the Nike Free Flyknit yesterday, but today, Sneaker News is bringing you an exclusive look at four colorways of this August release. Starting things off is the clean Volt/Grey combination on the Flyknit upper, with a slightly more saturated Electric Green being intertwined with the upper knit. These will certainly turn heads once they release in a few weeks, so check out the additional photos below and stay tuned for more previews of the Nike Free Flyknit.
