Nike recently developed the HyperAdapt 1.0, a self-tying and self-tightening shoe. HyperAdapt 1.0 was inspired by the movie Back to the Future, and the dreams of the directors have become reality. The shoe itself is really cool, but how does the shoe self-tighten? What makes that happen? Here’s how it works.

An engine placed in the sole of the shoe, called the Lace Engine, is attached to and powers the Fit System, which is the fly wire that runs through the shoe on both sides, covering your feet. The Lace Engine is activated by a sensor in the heel of the shoe that goes off when you step into the shoe. The engine runs and tightens the Fit System around your foot. The tightening stops when sensors detect the natural tension in your foot. There are also lights on the shoe. Lights go off when you step in as the laces are tightening. There is also a light on the side of the engine that indicates how much battery charge the shoes have left. Blue lights indicate full charge, yellow indicates that about 50% charge remains, and red indicates low battery. The HyperAdapt charger magnetically connects to the battery in the sole of the shoe. The shoe takes around three hours to charge and lasts about two weeks.

This shoe is amazing. It took many people and a lot of knowledge on a variety of different subjects, from batteries to engines and motors to design to make this shoe. The shoe also relates to engineering because it solves a problem, and that problem was that athletes had to be able to adjust their shoes quickly while playing their sport. The self-tying shoes eliminate actual laces, fit to your foot, and allow you to loosen or tighten your shoes in a fraction of a second. The HyperAdapt 1.0 is really a cool shoe and a marvel of engineering.
