Nike is raffling off 89 pairs of its "Back to the Future" self-lacing sneakers.
The special edition Nike Mags are replicas of the shoes worn by Marty McFly in the movie.
Raffle tickets are $10. The lottery, which can be found here, closes Oct. 11.
All proceeds will benefit the Michael J. Fox Foundation, which is working to find a cure to Parkinson's disease. Fox played McFly in the "Back to the Future" movies.
Now the Mag sneakers are different than the Nike HyperAdapt self-lacing sneakers that will be released during the holidays, CNN Money reports.
