Powerlacing shoes

Powerlacing shoes were a type of auto-lacing shoe. Nike had manufactured a line of powerlacers.
Marty McFly wore a pair of Nike powerlacing shoes while posing as his son Martin McFly Jr. in 2015.
[edit] Behind the scenes
Although the self-lacing shoes appeared to be complicated technology, with remote controls and small motors, designed specifically for the film, Bob Gale explained in the commentary to the second film that the special effect was actually quite simple. The first shot was of Marty putting on the shoes and placing his feet on the ground. For the second shot, the prop shoes were bolted to a platform made of fake asphalt, with the laces ran down through holes. On cue, a stagehand would pull the laces tight and a light (behind the Nike logo) would switch on. Sound effects were added later to complete the illusion.
In 2008, Nike released a limited run of 300 pairs of shoes inspired by the powerlacing shoes in Part II.
