Remember Marty's self-tying shoes in Back to The Future??

Nike will introduce self-tying "power laces," as worn by Marty McFly in Back to the Future Part II next year.  It's unclear if the shoes will be available to the public or will go on auction.   In 2011, Nike auctioned 1500 "BTTF" inspired shoes with proceeds going the the Michael J Fox Foundation.
