The Willy Wonka golden ticket for sneaker heads is here, as Nike’s highly anticipated “Back to the Future” self-lacing sneakers might be arriving sooner than you think.

The sports apparel giant has opened a raffle online where hopefuls can now purchase tickets to potentially score a pair of the new Air Mags first worn decades ago by “Back to the Future” protagonist Marty McFly. Here is everything you need to know about procuring your very own pair of futuristic self-lacing kicks.

Nike is debuting its Air Mags “Back to the Future Part II” shoes in limited quantities and the sneaker brand will be raffling off only 100 pairs of the new shoes, the Independent reported Tuesday.

The original Marty McFly, Michael J. Fox, is back on board and the Michael J. Fox Foundation has teamed up with Nike on the limited-time offer.

Through its app and online, Nike is offering an unlimited number of raffle tickets for all. Tickets are going for $10 a pop and can now be purchased. The catch? They’re only available for a full week through Oct. 11. The lucky winning recipients of the new Air Mags will be notified Oct. 17. Those who are entering the contest must be residents of the U.S. or Canada.

All of the ticket proceeds will go to the Michael J. Fox foundation to help find a cure for Parkinson’s disease, according to the Nike website.

The sizes available for the Back to The Future Part II sneakers come in sizes 7, 9, 11 and 13.

To enter, click over to Nike’s raffle entry page here. A one-time $1 first-time purchase fee will be charged.

For those who don’t score a pair through the raffle (most of you), stay tuned for Nike’s HyperAdapt 1.0 sneakers, which are expected to debut Nov. 28.
