Belgian fashion designer Kris Van Assche was tapped by adidas to collaborate on the latest iteration of the Ultra Boost, which was released in June 2015. This performance running shoe features a Primeknit upper adorned with an argyle print, showcasing a sophisticated combination of black, grey, and white hues. The diamond pattern, commonly seen on knit sweaters, is expertly juxtaposed with solid black accents on the midfoot cage and heel counter. To add a vibrant touch, a neon green rubber outsole completes the design with a pop of color.
