Nike first announced its upcoming self-lacing sneaker in March, and Wired reported on the shoes’ jaw-dropping capabilities in the video above in October. But now we have even more information on the seemingly magical HyperAdapt 1.0, which will be available for purchase Dec. 1.

Before you Marty McFly to your local Nike store for a pair of your own, be forewarned: You won’t be able to get your hands on a pair without a hefty wad of cash ― $720 ― and an appointment.

The super cool sneaks contain a sensor that automatically starts the self-lacing mechanism when you insert your feet, plus two buttons to loosen or tighten the laces to the wearer’s desire. The lacing system works off a rechargeable battery and the shoes boast an LED light to display how much battery is left.

As Wired explains in the video above, the sneakers are said to be ideal in an athletic event like a marathon or basketball game, when every second spent tying and re-tying shoes is crucial. Or, you know, when you want to impress your friends.
