Digitsole presents Back to the Future-style self-lacing trainers

Footwear company Digitsole's Smartshoes connect to the wearer's smartphone or smartwatch to warm cold feet, track footsteps, and lace themselves up like the Nike trainers worn in sci-fi film Back to the Future II. Launched at the CES tech fair this week, the trainer features laces that are hidden beneath the tongue of the shoe, and which can be tightened or loosened using an app. The function is reminiscent of the self-lacing Nike Air MAG sneakers worn by actor Michael J Fox in 1989 movie Back to the Future II. Nike unveiled the first working pair of the trainers last year, with a video showing Fox testing out their “power laces“ function.
