Adidas recently combined its Boost and Primeknit technologies for the first time within the U.S. … in the form of the adizero Prime Boost. The brand sent us over a pair, and we offer a closer look.

The new Boost running shoes feature Adidas’ energy-returning foam midsole, as well as a Primeknit upper constructed by digital knitting technology, carefully engineered to provide a precision fit that keeps your foot locked in place. The environmentally friendly shoe’s sole uses the same design as the adizero Adios Boost, which has been worn by winners of 17 major marathons thus far.

The adizero Prime Boost is available now at adidas retailers and for $200 USD.
