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