Michael J Fox tries on first pair of Back to the Future Nike shoes

Michael J Fox tries Nike's first pair of Back to the Future self-lacing shoes

Nike has celebrated Back to the Future day by presenting actor Michael J Fox with a pair of the self-lacing shoes he wore in the 1985 movie Back to the Future II.

Fox today released a video of himself wearing the futuristic shoes, which were one of many predictions about the future made in the time-travel movie.

The high-top Nike Air MAG sneakers were worn by the character Marty McFly, played by Fox, when he was transported from 1985 to 21 October 2015.

Nike intends to release the sneakers, which are equipped with "power laces" that tighten on their own when feet are placed inside, next year.

"We started creating something for fiction and we turned it into fact, inventing a new technology that will benefit all athletes," said Nike CEO Mark Parker in a statement published today on the company's website.

In a handwritten letter sent to Fox and posted on Twitter, Nike shoe designer Tinker Hatfield said: "As the first most celebrated wearer of the Nike Air MAG, we wanted you to be the first to receive a living pair."

"In addition to your personal pair, we're creating more pairs for support in the aid of the Michael J Fox Foundation in 2016," Hatfield added, citing the charity Fox founded to support research for Parkinson's Disease.

The organisation tweeted: "This is real. This is today. Coming spring 2016."

In 2011, Nike released 1,500 pairs of the footwear without the self-lacing technology. The shoes were auctioned on eBay, raising over $4.7 million (£3.1 million) for Fox's foundation.

The grey and white designs featured battery-powered LEDs embedded in the soles and heel, as well as a light-up Nike logo on the strap.

Nike said this January that it hoped to release a version of McFly's self-lacing sneaker by the end of 2015.

The company filed a US Patent for self-lacing shoes in July 2014, featuring motorised rollers embedded in the soles. These would be activated by a button on the side of the shoe or would respond to changes in weight. Once activated, the laces would wrap around themselves and create a tightening effect.

Other technologies featured in the film that have become reality, or near-reality, include holobillboards, hovercams (aka drone-mounted cameras), and wearable technology.
