- "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!' "

Power-lacing shoes were a type of footwear with shoelace-like straps that automatically tightened to secure the foot within the shoe.
