This pair uses the same basic equation as the recently released white/black, "Pale Grey," and "Bright Citron" pairs, mixing its black bits with light blue Flyknit. And, like those Flyknits, the silhouette is pretty much the same as when this sneaker debuted in 2012, save for the absence of Nike+ technology.
According to Nike, the specific shade here is inspired by "wispy white clouds against a blue sky."
