Here is the video preview of the upcoming Nike MAG sneaker. The sneaker is part of a very limited run, in which only 1,500 pairs of the Nike MAG 2011 are available, and 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 Nike MAG shoes 2011 will be made available via eBayâ€™s Fashion Vault. The auction started yesterday, September 8, at 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. Go get your pair NOW.
