The video: In 1989's Back to the Future Part II, teen time-traveler Marty McFly finds himself sporting sneakers that automatically embrace his feet. "Power laces, alright!" he exclaims as the film's fantasy Nikes automatically tighten (watch below). Now, Nike has actually patented the design and says that the self-lacing sneakers could be released by 2015, the year the movie is set. The patent application (view sketches here) reveals the intricate wiring and battery charging system that fuel the effect — not to mention heel lights and a flashing Nike logo on the top strap.
The reaction: If the shoes are actually released, says Charlie Sorrel in Wired, they would represent a "weird, time-warping paradox so perfectly mimicking those in the Back to the Future movies that the world might possibly end." They might even pave the way for other McFly inspired inventions — perhaps a hoverboard? Nobody knows just how closely the final product will mimic the originals, but "let's not mince words here," says Clay Dillow in Popular Science, because these shoes are awesome.
