About this product
Fashion designer Stella McCartney teamed up with Parley for the Oceans on this Ultra Boost X from March 2017. The uncaged low-profile runner, distinguished by a unique adaptive arch that molds to the foot, features a monochromatic Chalk White finish throughout. A Primeknit upper made with Parley Ocean Plastic, a performance yarn made from recycled ocean plastics, sits atop a Boost midsole.
