Everyone remembers the power laces Marty McFly used on his Nike shoes from Back To The Future 2. While Nike hasn't quite mastered the technology to make it a reality, instructables.com went the extra mile.
Called "The Auto Lace Shoe," blakebevin created a 9-step guide to creating your own version. A general overview is to "step into the shoe and a force sensor reads the pressure of your foot and activates two servo motors, which apply tension to the laces, tightening the shoe."
Pretty simple huh? Where would sports be without Science Fiction tv?
