Background:

I'm sure I'm dating myself but the "Back To The Future" series was just old school fun.
Up for grabs on eBay is Marty McFly's Nike's.
From the auction, the Nike engineers's description is as follows
The one and only original prototype of the Nike shoes Michael J. Fox wore in the movie Back To the Future II. You are bidding on a single shoe, not a pair. The shoe was designed as a working model, not a practical shoe, although it can be worn. It was worn once to the premiere of the movie in Beaverton, Oregon, and again by Michael J. Fox in Hollywood at a test fitting.
Back in 1989 I worked in the Nike Sport Research Lab as the Electronics Technician. The original BTF2 shoes for the movie were built by hand in the Nike Sample Room, and I was the one who designed and installed the electronics for them.
They were originally called "Slamball Shoes," and that's what most people called them around Nike. There was supposed to have been a scene in the movie in which Marty plays Slamball, a game like 3D racquetball where the participants wear magnetic shoes which allow them to climb up the walls. That scene was never shot because the cost of building a huge room on gimbals to create the effect was too great.
The REAL name of the shoes in Marty McFly's world of 2015 was the "Nike Mag" because of their magnetic properties, and that's what is molded in the back of the heel.
With just under 48 hours remainiing, this auction has 24 bids and the current high bid is $2600.00.
What will this auction end at?
