Contestants can enter the raffle online and can purchase an unlimited number of $10 tickets.

All of the proceeds raised in the raffle will be donated to "Back to the Future" star Michael J. Fox's foundation to help find a cure for Parkinson's disease.

Fox, who was diagnosed with Parkinson's in 1991, debuted the sneakers last year.

"Though it initially shared only a few seconds of screen time with Michael, the idea behind the Nike Mag unlocked something much bigger at Nike," Nike chairman and CEO Mark Parker said in a statement. "It sent us down an uncharted path of innovation, but it also opened our eyes to our ability to fight some of the world’s biggest challenges. We feel privileged for the opportunity to raise even more awareness for the fight against Parkinson's."

The Nike Mag sneakers feature Nike's new HyperAdapt system, which uses a sensor that responds to the weight of a wearer's foot to automatically lace the shoes. The heels of the shoes light up to signal when the shoe is tightening and when the batteries need to be charged.

The raffled sneakers will only be available in U.S. men's sizes 7, 9, 11 and 13.

The raffle closes Oct. 11, and winners will be notified on Oct. 17. 

Shoes with HyperAdapt technology will be available in the U.S. at select Nike retail locations starting Nov. 28, according to Nike's public relations director, Heidi Burgett.
