First introduced in 2018, the adidas Y-3 Kaiwa instantly became popular with Yohji Yamamoto fans. Relaunched in June 2019, the Y-3 Kaiwa 'Core Black’ features a sleek all-black colorway. The upper is constructed from premium leather while stretchy neoprene appears on the collar and heel with a suede heel tab. The high-cut tongue provides a hint of contrast with a white Y-3 and Yohji Yamamoto's stitched signature. Beneath, black pods extend out from the midsole adding interest.
