And yes, these were the self lacing kind from Back to the Future Part II (1989) they were sold by the Michael J. Fox Foundation on eBay. Its clearly a collectors item, since you can see in the image above, the shoe is falling almost apart. But I'm happy that the crumbs were part of the auction which makes these shoes almost complete again. No word, as far as I saw, about if the self lacing function still works or not. Congratulations on the winner - having this shoe displayed in your living room is definitely a great conversation starter.
P.S. It's already 2018, we're all waiting for that promised Hoverboard!
