I've always wanted a pair of Marty McFly's auto-lacing shows from Back to the Future II, and it appears now I might get the chance. Nike has sent out invitations to an event being held in Los Angeles tomorrow hinting at the existence of, you guessed it, the Air Mags. The invitation included a pair of Doc's aluminum shades and a bundle of Back to the Future merchandise. Nike did patent the Mags' power laces last year, so it could be an actual release this time.
