Self-lacing sneakers seem to be a thing of Marty McFly’s dreams, but Nike wants to make them a reality and has filed the official patent to do so. Inside the sole of the shoe, a power source pumps a motor that can be activated by a flip of a discreet switch. When the motor runs, it cranks a spool of wire that reels in the laces, tightening them to fit as if you tied them yourself. The self-lacing sneakers are complete with an ankle cinching system and on-board rechargeable battery.

Nike doesn’t have a set schedule to release the self-lacing sneakers but the patent proves it's in the works.
