The Nike MAG is no longer the “greatest shoe never made.” The mythical shoe that originally captured the imagination of audiences in Back to the Future II is being released — and they’re here to help create a future without Parkinson’s disease. 1,500 pairs of the 2011 Nike MAG will be auctioned on eBay with all net proceeds going directly to The Michael J. Fox Foundation. Each day for the duration of the ten-day auction, 150 pairs of the 2011 Nike MAG shoes will be made available via eBay’s Fashion Vault. The auction starts at September 8, 8:30 p.m. PST, and will end September 18. Thanks to a previous 50 million dollar match given to The Michael J. Fox Foundation, all donations will be matched, effectively doubling the contributions from the auction.
