Dreams do come true. Nike is releasing Marty's mythical shoe from Back to the Future II. In addition to the glowing LEDs and all the McFly style you can handle, the Nike MAG finally brings power-lacing to your feet. Yes, this is real. In the brief video below, Michael J. Fox, appropriately the first recipient of the shoes, tries them on for the first time. "The result is an individually responsive system that senses the wearer's motion to provide adaptive on-demand comfort and support," Nike says. "But this is just the first iteration." Meaning, expect to see power laces in other Nike shoes sooner than you think. The limited edition MAGs will be available via auction in Spring 2016, with all proceeds going to the Michael J. Fox Foundation for Parkinson's Research.
