Nike announced today the 2011 Nike Mag shoe–a wearable replica of Marty McFly’s shoes from Back to the Future II. The shoe company made only 1500 pairs, and they will be auctioned off on ebay here with proceeds going to the Michael J. Fox Foundation for Parkinson’s Research. Auctions will run for 10 days with 150 pairs being sold per day. If you love BTTF, love awesome shoes, and love helping a great cause, head over to the auction before they end on September 18 and place a winning bid. If you are poor like me and likely cannot afford the awesome Nike Mag, you can also donate to the cause here.
