Made in collaboration with the British fashion designer, the Stella McCartney x women’s adidas PulseBoost HD Mid ‘Utility Black’ merges boundary-pushing style with modern performance technology. The cold-weather running shoe utilizes a black and white Primeknit upper with an extended sock-like collar and glossy no-sew overlays for lightweight support. A high-density Boost is reinforced by a Continental rubber outsole for durable traction on wet and dry surfaces.
