One of MICHAEL J. FOX's self-tying shoes from the 1989 flick "Back to the Future 2" sold on eBay for $92,100. It was the LEFT shoe, and yes, Michael actually wore it in the movie.
Obviously, the shoe doesn't REALLY tie itself . . . the technology wasn't there in 1989. But in 2016 Nike did produce 89 pairs of LEGIT self-tying shoes.
The 1989 movie shoes are basically falling apart at this point . . . but obviously they're still worth a few bucks.
