Cristiano Ronaldo is one of the best athletes in the world, and Nike also realizes he has one heck of a social following. Nike allowed Cristiano Ronaldo to try out their power-lacing new HyperAdapt 1.0 kicks. The shoes are a marvel of modern technology in which the shoes actually lace themselves as soon as someone puts them on.

Nike explains the amazing shoes and their technology:

Welcome the Nike HyperAdapt 1.0, the first performance vehicle for Nike’s latest platform breakthrough, adaptive lacing. The shoe translates deep research in digital, electrical and mechanical engineering into a product designed for movement. It challenges traditional understanding of fit, proposing an ultimate solution to individual idiosyncrasies in lacing and tension preference.

Functional simplicity reduces a typical athlete concern, distraction. “When you step in, your heel will hit a sensor and the system will automatically tighten,” explains Tiffany Beers, Senior Innovator, NIKE, Inc., and the project’s technical lead. “Then there are two buttons on the side to tighten and loosen. You can adjust it until it’s perfect.”

Here is a little video also showing off the kicks.

You can check out Ronaldo’s reaction to the shoes below courtesy of his Instagram page.

Wow! Thanks @nike for letting me be the first athlete in the world to try the new HyperAdapt 1.0 #nike2016 #nikeinnovation
