The adidas UltraBoost DNA CC_1 ‘Legend Ink Gradient’ showcases a monochromatic finish on a running shoe that borrows cooling technology from the brand’s retro Climacool line. Aerodynamic air channels are built into the blacked-out Primeknit upper, made in part with recycled Parley Ocean Plastic and zero virgin polyester. Responsive cushioning arrives via a full-length Boost midsole, rendered in a color-fade effect and supported by a Stretchweb Continental rubber outsole.
