All the nostalgia around Nike's self-lacing shoe, the 2016 Mag, came together in a major way for a great cause. Today, the sportswear titan revealed it raised $6.75 million through its online raffle and two auctions, with all proceeds going to The Michael J. Fox Foundation. The money, as a refresher, will help the organization try to find a cure for Parkinson's disease. Michael J. Fox, who starred in the Back to the Future II film that made the sneakers popular, suffers from Parkinson's himself.
