Marty's Nike MAG power-lacing shoes, now all laced up and ready to go.
- "Marty had slipped the shoes on his feet, but they were still loose, a lot like the [auto-adjusting and auto-drying] jacket a moment ago, and he could see no way to tie them. Except there was a pad — like the one on his jacket — on the right sneaker. After a moment's hesitation, he pressed it softly. / The sneakers zip-laced themselves shut. / "Power laces!" Marty cheered. "All right!" "
- —From Back to the Future Part II by Craig Shaw Gardner (quote, page 20)
Power-lacing shoes were a type of footwear in 2015 with shoelace-like straps that automatically tightened to secure the foot within the shoe.
History[]
Nike manufactured a line of power-lacing sports shoes named the Nike MAG. Dr. Emmett Brown produced a pair of these futuristic sneakers from a Nike Footwear bag, along with an auto-adjusting and auto-drying jacket and a color-shifting lenticular baseball cap, which were worn by Marty McFly while posing as his son, Marty Jr., in 2015.
