Great Scott! "Back to the Future" self-lacing shoes are here!

Nike has revealed a line of self-lacing trainers, the Nike Hyperadapt 1.0. The shoes, which will launch later this year, are the first to feature what the sportswear brand is calling "electro-adaptive reactive laces (EARL)".

Activated by sensors in the sole, the EARL system adapts to the foot shape and weight distribution of the wearer. The laces are controlled by a system of pulleys, and can also be tightened or loosened with a button on the upper. 

The EARL system is powered by an in-shoe battery with lifespan of "about two weeks" between charges, according to designer Tiffany Beers. The same battery will power an LED inside the sole, which will indicate battery life.
