You Can Finally Own Marty McFly’s Power-Lacing Nike Sneakers

Great Scott! The future is finally here, friends.

After announcing last year that they’d cracked the technology to create a working version of Marty McFly’s power-lacing sneakers from Back to the Future Part II, Nike has, at long last, revealed the details behind the Air Mag’s public rollout.

In order to get your grubby mitts on your pair, you’re gonna need a whole lot of luck: only 89 pairs are available, and you’ll have to win the right to purchase yours via a raffle. The tickets cost $10 USD a piece, and all funds will go to the Michael J. Fox Foundation for Parkinson’s Research. You have until October 11th to buy them here, and the winners will be announced on October 17th.
