Nike Mag Marty McFly [Back to the Future II] Prototype

Why buy a pair of the Marty McFly inspired Nike Hyperdunk when you can have the real thing? Well not exactly, but you can become the exclusive owner of the Marty McFly prototype sneaker, which was uses to make the shoe Micheal J. Fox wore in the movie Back to the Future II. The single prototype sneaker (not the complete pair) is now on good old eBay for auction and won’t end till July 20th, so you can still have time to place your bid. But, you better have a couple thousand dollars laying around because the last time we checked the bid was at $2,425. The shoe features words “Nike Mag” on the back heel, and there’s working LED lights on the mid-sole and ankle strap. Click HERE to check out the auction.

This is IT. 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.

The lights in the side of the midsole and the Nike logo on the ankle strap are electro-luminescent panels, and there is an array of six randomly flashing LEDs on the side of the heel that were never visible in the movie

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.

The shoe is in “good” condition for what it is, but since the polyurethane midsole and fabric body of the shoe were simply spray-painted in the suggested color, some of the paint has flaked off over time. The LEDs, the E-L panel on the ankle strap, and one of the two E-L panels on the midsole still work. The other midsole panel comes on if you flex the shoe slightly. I originally thought I could get away with a rigid connection between those two panels, but it turned out that the flexing of the shoe during wear broke the connection. It might be fixable with some delicate surgery, but I never had the guts to try it.

The included power/electronics pack is hard-wired to the shoe, and requires two 9 volt batteries to operate.

I believe the shoe was built as a men’s size 9, although I couldn’t swear to it. It is whatever size Fox was at the time.

The shoe comes with a color photocopy of the original design drawing by Nike’s Tinker Hatfield (the designer of all of the Air Jordans, among many other things).

I’m happy to provide any more information I can, or additional photos you might like.

UPS Ground shipping is free, any other carrier or method at the actual cost of the service. I am willing to ship worldwide to any legitimate bidder.

Immediate payment is expected. A winning bidder who fails to pay within 7 days will forfeit the right to buy the shoe and it will be re-listed.

Good Luck!
