When the evening air turns cool, the Yeezy x Adidas Boost 380 'Onyx' sneakers bring a dark, gentle pulse to your night out. Woven in knit fabric, the upper fits like a cozy sock with an elastic ankle cuff and a sheer mesh side window for cooling air. Below, a full-length Boost cushion sits inside a protective shell, supported by a rubber sole with herringbone tread.
