We’re about a year past the future the first Back to the Future envisioned, and it’s safe to say reality is looking a little more bleak compared to the world of that classic blockbuster. But we haven’t totally dropped the ball. To celebrate the film Nike went ahead and actually made a working pair of the self-lacing sneakers teased in that 80s classic, the nike casual shoes. And now, the real Nike Mags have become the world’s most expensive sneakers.

For years, you’ll fantasize about these fictional sneakers, later named the nike womens trainers. In that time, you’ll also collect all kinds of real shoes: mostly Jordans, which are coincidentally designed by Tinker Hatfield, the same genius who made the Mags. But they all will just temporarily satisfy your desire for that special pair.

The Back to the Future version is fully functional, with buttons by the collar to tighten and loosen the shoes as well as turn on the lights along the bottom (because a futuristic shoe needs to have lights). A sensor in the shoe can also tighten the shoes automatically while you go. nike mens shoes says battery life is around two weeks with the lights off. You can charge the shoes through a cable that connects to the back. Charging takes three to four hours.
