Nike revealed the launch details for the 2016 Nike Mag yesterday, featuring an online raffle and a $10 lottery ticket as the cost of admission. Just 89 pairs were made, so the likelihood of winning a pair is like winning the actual lottery, but the upside is that the money is going to a worthwhile cause, the Michael J. Fox Foundation for Parkinson's Research. The Back to the Future star made an appearance this morning on ABC's Good Morning America, sitting down with George Stephanopoulos to show off the Nike Mag and also talk up the great work his foundation has done.
