Yesterday, I posted about these hot new, official Nike brand MAG sneakers that are perfect visual replicas of those worn by Marty McFly in Back to the Future Part 2 and wondered if they have the trademark power laces that the ones in the movie did. Tragically, they don’t, but to make up for it, here’s a promo for the charity auctions taking place right now that allow you to own your own pair of these special shoes. The promo stars Bill Hader, but more importantly, Christopher Lloyd makes a cameo as Doc Brown! And man, he looks exactly the same!
