Nike Mags (Back to the Future 2)
Marty McFly's self-tying kicks from 1989's Back to the Future Part 2 are a given, when it comes to cool movie gadgets. As is his hoverboard, but that's one for another feature. A limited run of 1,500 lookalike Nike Mag replicas were auctioned off in 2011, with the proceeds going to the Michael J. Fox Foundation for Parkinson's Research. Now that it's 2015, the year Marty travelled to in the film, Nike has confirmed that it is working on Nike Air Mags with actual self-tightening 'Powerlaces'. Great Scott!
