If you were a fan of those self-lacing shoes Marty McFly wore in “Back to the Future II” you just might be able to win a pair.

Nike is raffling 89 fully functioning, self-lacing 2016 limited-edition Nike Mag shoes in an online lottery.

The shoes have embedded white laces that electronically cinch at the press of a button and blue neon lights on the sides and heels and Nike logo at the ankle.

Customers can donate $10 per entry with all proceeds going to the Michael J. Fox Foundation for Parkinson’s Research.

There is no limit to the number of entries and winners will be notified on Oct. 17.

To enter, visit nike.com/mag by Oct. 11.
