Move over Kanye, there's a new pair of trainers in town and they've got "power laces". (That's individually responsive laces, for those not in the know.)
Yep, Back to the Future's self-lacing trainers are finally a reality, as Nike has launched the limited-edition Nike Mag - worn by Marty McFly three decades ago.
In the video below, Nike CEO Mark Parker announces the launch of the super-smart Mags.
The high-tech kicks are made in partnership with the Michael J Fox Foundation (MJFF) - but there are fewer than 100 pairs available globally AND you'll have to enter a draw to win.
Open right now, the draw runs until October 11, so you'd better hurry. Each ticket costs $10 - with no limit on the number of tickets you can buy.
And don't worry, it's not going to be a huge waste of money if you don't manage to get a pair of Nike Mags because 100% of the proceeds will go to the MJFF to help find a cure for Parkinson's.
Last month, Nike dropped the launch date for its Nike HyperAdapt 1.0 sneakers - another pair of shoes with self-powered laces that tighten around you when you slip them on, with a sensor in each sole recognising when your foot is inside.
The sides and laces then pull, similarly to the Nike Mags, as users can also loosen and strengthen the grip with a button on either side.
Unfortunately, the futuristic shoes will only be available in the US initially, with a handful of retailers offering the HyperAdapt fun from its release date on November 28.
