'Siri, release my shoes': Nike unveils Back To The Future-style trainers

Self-tying shoes may have arrived a few years later than Back To The Future predicted, but could Marty McFly control his pair with his voice?

Nike has developed a so-called FitAdapt lacing system that uses a motor to tighten or loosen its trainers, and the newest pair to sport the tech - the Adapt Huaraches - can be untied using Siri.

Users can tell the voice assistant to "release my shoes" via the Nike Adapt app on their iPhone or Apple Watch, and the software can also change the colour of LED lights on the bottom of the shoes.

The sportswear giant said its latest version of FitAdapt "allows for a wider array of personal preferences amid various environments and situations", rather than just being suited to a dedicated running shoe.

Its announcement of the new high-tech trainers did not come with a price, but the Nike Adapt BB shoes featuring similar technology went on sale for more than £300 earlier this year.

Prices have come down significantly since Nike released its first self-lacing trainers in 2016, when the HyperAdapt 1.0 hit the market in the US for a whopping $720.

It put the Back To The Future dream out of reach for most people, but it may become more of a realistic prospect for some if prices continue to fall.

The Adapt Huaraches trainers will be available from 13 September at select retailers and the SNEAKRS app.

Unfortunately, there is still no sign of a proper hoverboard.
