The result of a longstanding collaboration between adidas and cutting-edge Japanese designer Yohji Yamamoto, the Y-3 Saikou 'Night Indigo' features a lightweight Primeknit upper with an exaggerated tongue and heel liner. Mesh panels enhance the middle of the silhouette, with cutouts exposing the lacing system, all in a rich blue. A white mudguard with soft ridges juts up into the vamp, complemented by a responsive Boost midsole just below.
