Today is your last day to enter for a chance to own Nike’s self lacing Mag sneakers. Based on the iconic shoes from Back To The Future 2, Nike last week announced the availability of the footwear. Like the 2011 release of the non-self-lacing version, the shoe is extremely limited in quantity; only 89 pairs are being made available. Last year, when the shoes were originally announced, it was stated they would be released via auction in Spring 2016. Nike not only missed their Spring release date, but the shoes also aren’t available via auction. For most of us though, that isn’t necessarily bad news. Unless you had a tremendous amount of money to drop on a pair of sneakers (which you more than likely would never risk wearing), there was no chance you would own a pair. At some point over the past 12 months Nike had a change of heart and instead decided to raffle the shoes off. Virtual raffle tickets can be purchased from $10 a piece from Nike and all proceeds go to the Michael J. Fox Foundation. Even if you don’t win, you are helping a fantastic nonprofit in their efforts to cure Parkinson’s. Today is the last day to enter to win an elusive Nike Mag; the drawing closes at 11:59pm ET. If you have been on the fence about entering or have been thinking about buying some additional tickets, to help encourage you the Michael J. Fox foundation will match dollar-to-dollar all donations today!
