Marty McFly’s iconic self-lacing Nike Mags just got a smart-phone upgrade. Inspired by the film “Back to the Future II,” Nike has cooked up a new basketball trainer with a “lace engine” that remembers the perfect tightness via a smartphone app.
Nike released the first ever self-lacing shoes in 2016, one year too late for fans of the classic 1980s movie, “Back to the Future II,” which was set in 2015.
