Originally from the 1989 sequel, Back to the Future II, the Nike MAG 2011 was one of the most iconic pairs to ever release, and instantly made history. Nike auctioned 1,500 pairs to the public to benefit the Michael J. Fox Foundation for Parkinson’s Research. The release raised US$9 million for the foundation after a historic auction. This is one of the few pairs in existence to have ever been signed by Michael J Fox himself.
