UPDATED!! Not Self-Lacing But For A Good Cause! THIS IS REAL: Marty McFly's Self-Lacing Sneakers Are Coming

UPDATED: The bad news: The 2011 Nike MAG will not actually be a self-lacing shoe.  Also, Nike only manufactured 1500 pairs.  The good news: All 1500 pairs will be auctioned off on eBay starting tonight at 11:30PM EST at a rate of 150 a day and the net proceeds will go to the Michael J.

And the final kicker?  Michael J. Fox will be the guest on David Letterman tonight.  This will mark the first time in years I'll make a point to watch Letterman, and it'll be solely for the purpose of looking at Fox's feet.

For the record, this is only serving to further convince me that I'll be able to own a hoverboard within the next four years.
