History[]
Dr. Emmett Brown gave Marty McFly a pair of these shoes to wear on Wednesday, October 21, 2015, which he produced from a large futuristic Nike Footwear bag he carried aboard the DeLorean time machine.
Marty retained the shoes during a hoverboard chase while escaping from Griff's gang. He later changed back into his regular shoes while Doc was getting Jennifer Parker from her future residence.
