This is a Nike t-shirt for the Nike Hyperdunk "Marty McFly" edition that released in 2008. The "Marty McFLy" edition Hyperdunk was a prequel to the actual Nike Air Mag which released in 2011 and looked similarly enough to the shoe worn in the movie Back To The Future 2. This shoe was VERY limited upon release and has grown increasingly difficult to find. This shirt features an outline of the shoe with the words "Hyperdunk 2015" underneath. These shirts were also very limited with only about 100 being produced. Be sure to add this to your Nike Basketball collection.
