Did you know it's already been 26 years since "Back to the Future II" came out? The sci-fi classic made plenty of predictions about the future, and one of them might finally be coming true. Engineers in Germany have designed a shoe that will tie itself.

A team of engineers at the University of Freiburg in Germany created the shoes. In addition to tying itself, the shoe can also shape itself to fit your foot and loosen the laces when you want to take them off.

Simply slip the trainer on and pressure sensors will tell the "smart shoe" when your foot is in position, triggering a tiny motor in the heel that pulls the laces tight.

To get the shoe off, wearers just click their heels together twice to release a spring that loosens the laces. You don't even have to plug in the shoe to recharge it. It uses magnets in each shoe to collect the power generated by your feet swinging while you walk. It can also be charged on a wireless charging mat.
