McFlys actually exist.
Sneaker: Nike Air Mag
Back in 1989, the definition of "sneakerhead" could have been this: All you cared about in Back To The Future II was Marty McFly's sneakers. Forget the hoverboard, forget the DeLorean, you wanted a pair of Air MAGs and you wanted them as soon as possible. Well, you didn't have to wait until 2015, but it was close. Nike released a limited number of the Tinker Hatfield designed hightops via auction in 2011, with all proceeds going to Michael J. Fox's Parkinson's foundation. A great sneaker for a great cause-it doesn't get better.
