For the Spring of 2019, Y-3 advances the iconic Y-3 Runner 4D, presenting the shoe’s new bone-white midsole, which is crafted with the latest evolution of adidas 4D technology. Inspired by the ALPHAEDGE 4D midsole, it evolves the breakthrough properties of ADIDAS 4D and features a wider foot bed and a thicker, higher midsole for greater multi-directional stability; higher energy return in specific areas for more powerful bursts of movement; and a new Continental rubber outsole for improved grip on any surface. This debut colorway comes covered in white throughout the two-layer knit upper along with black accents and Yohji’s signature added to the lower tongue.
