'Back To The Future'-style self-lacing trainers are set to become a reality in 2015, according to a Nike designer.
Tinker Hatfield has said the company is working on power laces like those worn by time-travelling teenager Marty McFly in the classic film series.
He told trainer news website Sole Collector: "Are we gonna see power laces in 2015? To that, I say yes!"
Back To The Future II, set in 2015, includes a scene where McFly, played by Michael J Fox, slips on a pair of Nike High Tops that adjust automatically to his feet.
The company applied for a patent for "automatically lacing trainers" in 2010.
A year later Nike produced illuminating trainers based on those worn by McFly – the Nike Mag.
A total of 1,500 pairs were auctioned off to raise money for the Michael J Fox Foundation, raising £3.4m ($5.7m).
Fox has Parkinson’s and his organisation funds research into the disease.
Among those who bought the shoes were UK rapper Tinie Tempah - who spent £24,000 ($40,000) to own the first available pair - and fellow musicians Kanye West and Kid Cudi.
