Saw this first at iamagm.com, and while you might have to wait a few more years for power laces, it's still pretty cool. The Nike Mag, a replica of the shoe featured in Back to the Feature Part II has been made by Nike with 1500 pairs being auctioned on eBay to raise money for the Michael J. Fox Foundation for Parkinson's Research.
The commercial for the shoe features Kevin Durant, Saturday Night Live's Bill Hader and Doctor Emmett Brown himself, Christopher Lloyd.
And of course, the inspiration for the shoes.
