This Nike Dunk SB sneaker, styled after Marty McFly, is a perfect addition to any sneaker collection. The shoe features a low top design and comes in a wolf grey and white colorway with hints of light retro. The US shoe size is 6, and it is suitable for men. The style code is 313170-022, and the shoe was released on May 23, 2015. This athletic sneaker is a replacement box product from the Nike Dunk product line. The shoe is nicknamed Marty McFly and has a sleek design that is perfect for any casual occasion. The shoe shaft style is low top, and the color is gray. The shoe is pre-owned and has been well-maintained. Very little wear on this rare iconic shoe!!! I do not have the original box.
