Anyone remember those futuristic high tops Marty McFly wore in Back to the Future 2? Of course we do! But far be it for anyone to actually get their hands on a pair in the real-live breathing world…until now.

Nike produced the LED-laced rechargeable Nike Mag (or ‘magnetic levitation’) sneaker to help raise funds for the Michael J. Fox Foundation for Parkinson’s Research. The shoes, which are being auctioned off on eBay, are bidding at anywhere from $2,000 – $11,000. So at 1,500 pairs (which is the amount of shoes Nike produced for the limited edition run), that means beaucoup bucks for Fox’s charity.

In addition to 100% of the eBay sales going to the Foundation, Google co-founder Sergey Brin and his wife, Anne Wojcicki, have pledged to match the auction’s proceeds with a grant up to $50 million.

While, unlike the movie, the 2011 Nike Mags don’t actually lace themselves, they are at least helping people’s lives. Rapper Kid Cudi tweeted that he has already bought four pair, possibly taking after British rhymester Tinie Tempah, who paid $37.5K on the first pair of Nike Mags released. (Sneaker fetish much? Or, okay…maybe he just has a big heart.)

Each day, 150 pairs will be up for auction until September 18. Happy bidding, sneaker lovers!
