Last night a seemlingly innoculous Tweet from Nike Public Relations Director Heidi Burgett surfaced alluding to the potential arrival of the futuristic, self-lacing Nike Air Mag. In the minutes that followed, another hint dropped in the form of a Tweet from Nike directly to Michael J. Fox, simply stating, "See you tomorrow." Now CNBC anchor Sara Eisen is reporting that a Nike source confirms to her that the first pair of self-lacing Nike Mag shoes are indeed in NYC. Exact details on location or purpose aren't known yet, but it seems the cult-favorite film was more prophecy than fantasy. Stay tuned BTTF fans.
