All who have ever admired Marty McFly’s cool kicks from “Back to the Future II” now have a chance to bid on a pair of their own — and for a good cause. Nike announced Thursday that 150 pairs of the  futuristic high-tops would become available on eBay for 10 days, and  the proceeds would go to the Michael J. Fox Foundation for Parkinson’s Research.

“The project … brings together three very passionate audiences: the Parkinson’s community, sneakerheads and `Back to the Future’ fans,” Michael J. Fox said in a statement.

 The shoes — called Nike Air MAGs, were rebuilt to the exact specifications of the originals. The high-tops include a glowing sole and Nike logo that is activated with a simple pinch of the high-top’s ear. The only thing they don’t do is lace themselves.

It’s the shoe fans have been asking for. A few years ago, an online campaign called  McFly 2015, Make It Happen  urged Nike to make a version of the shoe for retail.

Even though the price of the limited-edition shoe may be out of reach for most people, Twitter lit up with comments from fans excited about the release.

“I’ve never worn sneaks in my life, but I NEED these,” @jacvanek wrote.

Another person proposed sharing the sneakers.

“Who wants to go halves on the Marty McFly Nikes from BTTF 2? Only about $40,000,” @cameronhurley wrote.

A tweeter  named Will Eurich was determined to get his feet into a pair and posted a screen shot of his $4,050 bid. “Wish me luck,” he wrote.

The auction ends Sept. 18.
