Immortalized in the 1989 film 'Back to the Future II,' the Nike Mag was finally released to the public in September 2011. It's an aesthetic matchup to its film counterpart, complete with an electroluminescent Nike logo on the strap and bright LED arrays on the midsole and heel. The 2011 production was limited to 1,500 pairs and released via eBay charity auctions where proceeds went directly to the Michael J. Fox Foundation to find a cure for Parkinson's disease.
