As a collaboration between adidas and American model Karlie Kloss, the Karlie Kloss x adidas women's X9000 'White Iridescent' running shoe is part of a larger collection. This particular shoe features a clean and minimalist design, with a white mesh upper that incorporates recycled content and tonal synthetic leather overlays. The monochromatic look is broken by the black lettering of 'Karlie Kloss' printed on the tongue. The shoe also offers responsive cushioning, thanks to its sculpted Boost midsole.
