These shoes are the sneakers worn in Back to the Future by Marty McFly that had self-adjusting power laces.

In the movie, assistants beneath the false floor tightened the shoes. Nike has worked for decades to perfect the self-lacing sneaker. The first pair was given to Michael J. Fox, who auctioned them to raise funds for Parkinson’s research.
