The Nike Air Flow was the follow up to the Nike Air Sock which eventually graduated into the Presto.  Earlier this year The Nike Air flow was turned into the Nike Lunar Flow.  Well, for purists this is wonderful news, Nike will be bringing back the Air Flow in all its original glory in two dope OG color ways.  Slated for a June release, you better start saving your penny’s now because choosing between both color ways will be next to impossible!
