2. Self-Lacing Sneakers

In the event you didn't have an extra $37,500 to spare to get your hands on a pair of the coveted 2011 Nike Air Mags, fear not; it isn't too late for you to live out your Back To The Future dreams with self-lacing kicks. In 2010, the inventive Blake Bevin showcased a pair that might just rival Marty McFly's. Thanks to an Arduino microcontroller and pressure sensitive plates, the sneaks detect when someone has stepped into them, and the laces are pulled tight to fit. "Great Scott!"
