Ever since Marty McFly threw on a pair of Nike Mags for the first time in Back to the Future II (1989), fans have been waiting for the day when sneakers could lace themselves. The company filed a patent for auto-lacing technology in 2010 and showed it in action with Michael J. Fox in 2015. Now, according to Complex, Nike has revealed that runners will soon be able to purchase the auto-lacing shoe in stores.

The Nike HyperAdapt 1.0 and its "adaptive lacing" system were introduced at a press event in New York City this week. With the help of sensors located in the heels, the lacing system activates as soon as the wearer puts the sneakers on. To adjust the fit, the wearer can press one of two buttons located on the side of each sneaker: the button with a plus sign to tighten, and the one with a minus sign to loosen.

While early prototypes came in the form of snowboard boots with a generator attached to the outside, the Nike HyperAdapt 1.0 features a small mechanism located under the foot.

Next up: Creating footwear that knows when the wearer wants a looser or tighter fit—and makes adjustments automatically. "That’s where we’re headed. In the future, product will come alive," Nike designer Tinker Hatfield said.

Nike hasn't yet shared the exact release date or price, but the company predicts that consumers will be able to purchase the Nike HyperAdapt 1.0 in three colors beginning this holiday season. The initial sale will only be open to Nike+ members.
