You remember the first time you saw Back to the Future II , don't you? We all dreamed of a world filled with hoverboards and self-lacing shoes , and now Nike's made the latter a reality... sort of. Marty McFly's favorite high tops are now called the 2011 Nike MAGs and look just like the kicks in the movie, though it appears that you'll have to lace 'em up the old-fashioned way. They'll only be on sale during a ten-day period starting tonight at 8:30PM Pacific Standard Time, and no amount of flux-capacitation can score you a pair if you miss that window. 150 sets of shoes will be auctioned on eBay's Fashion Vault each day (sorry, US bidders only), and all the net proceeds will go to The Michael J. Fox Foundation to further Parkinson's research. Not only that, all the money made will be doubled through matching contributions. Nice job, Nike, now about those hoverboards...
