Y3 Kozoko High Trainers in White / Black. The newly introduced Y-3 Kozoko High drew quite a reception at the Y3 SS17 runway show last year. Its stark white and black colourway is a head-turner and with the inclusion of the adidas BOOST sole unit with Torsion support, it provides a comfortable ride. Yohji Yamamoto and Y-3 branding adorn the toe-box and heel respectively whilst plush leather panels accent the sides. A neoprene upper offers a snug fit. A n adidas rubber outsole has been added for additional traction.
