Y-3, the brainchild of adidas and Japanese designer Yohji Yamamoto, brings the QR Run Boost back with a colorway from the adidas archives. The black neoprene upper is supported by black and white leather panels as well as a branded green tab, all worked into the lacing system. Visible Boost foam in the toe provides cushioning, while additional Y-3 branding emerges on the heel and tongue tag.
