Nike just announced a product that should cause "Back to the Future" fans to freak the heck out. The company revealed HyperAdapt 1.0, a self-lacing system triggered when you place your foot inside the shoe. Nike introduced the technology Wednesday by saying it has manifested the "unimaginable." Except it has been imagined. We saw a preview back in 1989 when Marty McFly donned a pair of Air Mags with power laces. And we've wanted them to be real ever since.
