UltraBOOST "Black/White Speckle" f36153

The adidas Ultra Boost 4.0 "Black/White Speckle" is a neutral running shoe that amplifies performance for runners of all kinds. The shoe is equipped with a black stretchy upper that's sprinkled with white flecks in the material. The Boost midsole, also seen in black here, marks a revolutionary turn for the Three Stripes brand as it relates to both style and comfort. A Stretchweb rubber outsole flexes with each step for adaptive comfort and provides extraordinary grip for added stability and secure push-off.
