After years of rumors, Nike is finally selling a run of Back to The Future shoes. These Nike Air Mags are like the ones that Marty McFly put on in the movie and they laced themselves up. The shoes are going for a few thousand on eBay and all the proceeds benefit Parkinson’s research. Sadly, all they do is light up and look cool, they’re not self-tying. Which is why this guy, who has a working prototype of a self-lacing shoe, should have gotten a production run instead.
