The adidas Yeezy Boost 380 'Alien Blue' offers a winter colourway of the lifestyle silhouette, highlighted by a Gray and Cream Primeknit upper with reflective details for improved visibility in low light conditions. A subtle green finish distinguishes the monofilament window that adds depth of texture to the lateral quarter panel of the shoe. The sock-like structure is mounted on a full-length Boost midsole, wrapped in a semi-translucent blue rubber cage and supported by a herringbone-patterned rubber outsole.
