Nike is indeed releasing a line of sneakers inspired by Back to the Future, but there's a couple catches.  First, the self-lacing feature that made the kicks so futuristic is not included on the Nike MAGs.  That seems like a waste to me, but I'd never own a pair anyway thanks to the second catch: Nike is producing just 1,500 pairs to auction off over the next week.  The auction begins over at Nike's Ebay page tonight at 8:30 PST and ends September 18.  All of the net proceeds go to the Michael J. Fox Foundation to research Parkinson's disease.Fox will appear on Late Show with David Letterman tonight to talk more about the shoes and the auction.  In the meantime, hit the jump for another commercial that shows off the features of the shoe (lots of lights!).[Update: We've added a commercial featuring Bill Hader and Christopher Lloyd plus new images after the jump.]If you're a massive Back to the Future geek (aren't we all?) with thousands of dollars to spare, there is no better cause than this.  I want to tell my grandkids, "Back to the Future cured Parkinson's disease."  Look how pretty:Though to be honest, I'm partial to the commercial we saw last night, titled "McFly's Closet":Update: The auction started just before I posted, and I should have checked back at the Ebay page before I did so.  Nike uploaded another commercial starring Bill Hader, Christopher Lloyd, and (awkwardly) Kevin Durant.  Back to the Future producer Frank Marshall directed the spot.Additionally, Nike posted six more images that show the MAG from every angle, including what it looks like sitting atop a Delorean.
