Michael J. Fox explained that the company will auction off 1,500 pairs of the shoes on eBay. The proceeds from the Nike Mags will go to the Michael J. Fox Foundation for Parkinson’s Research. This sum will be matched by Google co-founder, Sergey Brin, and his wife, Anne Wojciki, through the end of 2012.

The only downside? The shoes don’t have power-laces. But they do light up.

The company began teasing the announcement Wednesday, when they released a cryptic ad featuring rows and rows of the kicks. At the moment, the first 150 shoes released are going for around $4,000 a pair on the auction site.

To promote the sneakers, Nike has released an ad starring Christopher Lloyd as Dr. Emmett Brown, Bill Hader as a dude who sells shoes and basketball player Kevin Durant as Kevin Durant. Hader informs Doc Brown that the shoes don’t have power-lace — until 2015.

Update: The first pair of Nike Mags were auctioned off in Los Angeles last night and sold for $37,500! “Community’s” Joel McHale helped host the event and promised the buyer a puppy, TMZ reports.
