Following the release of the Stella McCartney x adidas 2016 spring/summer collection, the collaborative duo has unveiled a new Ultra Boost. Featuring a Primeknit upper in a white and blue base colorway, the Clima Cool running shoe is constructed with a sole support system exclusive to the Stella McCartney line. As with most BOOST runners, the molded synthetic and mesh midfoot cage provides optimal support that improves performance. Complementing pink laces and a tan tongue tab segment completes the striking look of the new Ultra Boost. Grab pair of these exclusive runners now at the Stella McCartney x adidas website.
