Nike designer Tinker Hatfield confirms McFly’s Self-Tying Power Laces for 2015.

In the movie, Back to the Future II, Marty McFly, played by Michael J. Fox, puts on a pair of Nike High Tops that automatically tighten and adjust to fit his feet called power laces. In 2011, Nike released a limited range of McFly’s Nike MAGs with manual laces, and now designer Tinker Hatfield has revealed the power laces will arrive in 2015.

The announcement about the power laces was made by Nike designer Tinker Hatfield because 2015 was the year Back to the Future II was set in. Speaking at the Jordan Brand Flight Lab in New Orleans, Hatfield told Sole Collector that power laces in 2015 will be release.

Rumors about the power laces have been rotating since 2010 when Nike applied a patent for automatically lacing trainers.

“The automatic lacing system provides a set of straps that can be automatically opened and closed to switch between a loosened and tightened position of the upper. The article further includes an automatic ankle cinching system that is configured to automatically adjust an ankle portion of the upper,” Nike stated.

The Back to the Future inspired Nike MAG range was launched in 2011 and only 1,500 models of the High Tops were made, and every pair was auctioned off on eBay.
