HOW IS BOOST MADE? To create Boost, thermoplastic polyurethane particles are expanded to form closed cells around tiny pockets of air. The resulting product is known as expanded thermoplastic polyurethane—or eTPU, for short.

adidas Boost technology is a product of the adidas Innovation Team (AIT) and German chemists BASF. It was created to bring together the formerly contradictory benefits of soft and responsive cushioning. At the time, EVA foam was the industry standard for performance running shoes.

Responsive cushioning and incredible energy return make Ultraboost shoes essential for runners who want top-notch comfort and support.

Those using this shoe for easy runs and long runs will do fine, while those wanting a shoe for uptempo or faster efforts may want to look elsewhere. The Adidas Ultraboost Light is a daily training shoe with a highly cushioned heel and a firmer forefoot.
