I know many of you went nuts after seeing the Nike Mag 2015, Nike’s real-life version of the sneakers worn by Marty McFly in Back to the Future II. Only 1500 pairs were produced, and they are all being sold via auction on eBay. 150 pairs will be listed each day, and all proceeds will go to the Michael J. Fox Foundation for Parkinson’s Research. If you are interested in bidding on a pair, here is a direct link to the search results. Don’t expect to get these for cheap however, most pairs are going for $2500 and up.
