If you are a fan of the Back to the Future series, this is one item that qualifies as a must have memorabilia. This is one half of the original prototype for the shoes used by Michael J. Fox in the movie - Back to the Future II. These shoes, made by Nike, are called the MAG. If you can remember the hype surrounding the movie when it was released, you would probably know that these caused quite a stir in those days. The lights in the side of the midsole and the Nike logo on the ankle strap have electro-luminescent panels and an array of six randomly flashing LEDs on the side of the heel that were never visible in the movie. Unfortunately, it's just one shoe, not a pair, making wearing them in the streets impossible. So, if you must have them just for the unique value that they hold, this just has to be in your collection. Ebay is the answer if you want to ask HOW?
