In the 1989 film, Back to the Future Part II, Marty and Doc travel to 2015. At one point in the film, Marty puts on self-lacing Nike Air Mags, which tied themselves. This was done with 2015 technology.
And news: Nike has made these shoes!
He still sounds like Marty McFly!
And on October 21, 2015, he and Christopher Lloyd went on the Jimmy Kimmel show and they reprised their Back to the Future roles as Marty McFly and Doc Brown.
And after that, Jimmy Kimmel interviewed Fox and he demonstrated the shoes he was wearing. It appears at the beginning of the video below.
He also talks about a Brooklyn commencement speech he gave and when he was shaking hands, one person showed him his "f**k you" finger. It was a pretty funny video.
Nike has debuted the shoe and it may be released later this year. If it is released, it will likely be VERY expensive.
