The Back To The Future star was given the trainers to mark 21 October, 2015, which was the date his character Marty McFly travelled to in the 1989 sequel.
Fox revealed he received a letter from the company reading: “As the first, most celebrated wearer of the Nike Air Mag we wanted you to be the first to receive a living pair.”
Fox, who has Parkinson’s disease, tweeted about the shoes through his foundation account before posting a video showing him trying them on.
“This is real. This is today. Coming spring 2016,” he wrote.
