OTRC: Michael J. Fox talks 'Marty McFly' shoes, cites 'obsessive' 'Back To The Future' fans

Bill Hader appears in a commercial for the 2011 Nike Mag sneakers, posted on Sept. 8, 2011. They are inspired by the 1989 film 'Back To The Future - Part 2.' / Michael J. Fox talks about Nike's new Nike Mag shoes in this video interview.

Michael J. Fox is excited about the release of Nike Mag sneakers, replicas of the shoes his character Marty McFly sported in the 1989 movie "Back To The Future - Part 2" that many fans of the trilogy have longed to possess.

However, as explained in a commercial for the sneakers, which stars Christopher Lloyd reprising his role of scientist Doc Brown, power laces are not included. The ad also features "Saturday Night Live" actor Bill Hader and NBA star Kevin Durant.

Nike announced on Thursday, September 8, that it would sell a collection of 1,500 such shoes on eBay and that all net proceeds would go to the Michael J. Fox Foundation, a charity that promotes efforts to find a cure for Parkinson's disease, an ailment the 50-year-old actor has suffered from for at least 20 years.

"This project is really exciting because it brings together three communities with a great passion," Fox said in a promotional video interview. "One is, obviously, the Parkinson's community that has a great passion for finding a cure for the disease. The other is the sneakerhead constituency ... and the other is 'Back To The Future' fans who have become, take it from me, pretty obsessive."

Fans of the trilogy have often staged conventions to celebrate the movies. Last year, Fox, Lloyd and Lea Thompson, who plays McFly's mother, reunited for an event to mark the 25th anniversary of "Back To The Future."

Fox visited the "Late Show With David Letterman" on Thursday night to introduce the Nike Mags. The eBay auction is set to end on September 18. The pairs of Nike Mag sneakers listed on Friday, September 9, showed ongoing bids that range between about $4,000 and $6,000.

In the "Back To The Future" films, Fox's character, teenager Marty McFly, and his friend, scientist Dr. Emmett "Doc" Brown, played by Christopher Lloyd, use a DeLorean car that functions as a time machine to travel through time to try and change events in their past and future. The final movie was released in 1990 and was set in the Wild West.

The second film is set in 2015 and features the sneakers, which lace themselves onto McFly's feet when he steps into them. While the Nike Mags currently listed on eBay do not come with power laces, two years ago, Nike did apply for patents to produce similar technology for future footwear.

(Did you know? Eric Stoltz was originally supposed to play Marty McFly. He even filmed scenes for the first 1985 film.)
