The adidas ZX 9000 ‘YCTN’ represents the letter ‘Y’ in the brand’s ‘A-ZX Series,’ spanning 26 distinct drops throughout 2020 and 2021 that explore the legendary ZX running franchise. Named after the Yucatan and inspired by traditional moccasin style footwear, this pair carries a mostly black upper crafted from a premium blend of suede, leather and nubuck. Contrast Z-shaped stitching encircles the toe box of the right shoe, while X-shaped stitching adorns the left.
