The adidas Yeezy Boost 380 Alien Blue delivers a wintry colorway of the lifestyle silhouette, highlighted by a grey and cream Primeknit upper with reflective detailing for enhanced visibility in low-light conditions. A subtle green finish distinguishes the monofilament window that adds textural depth to the sneakers lateral side panel. The sock-like build is mounted on a full-length Boost midsole, wrapped in a semi-translucent blue rubber cage and supported by a herringbone-tread rubber outsole.
