The “Alien Blue” marks the second time that Kanye West and adidas have used the “Alien” moniker on the Yeezy Boost 380. Like the original “Alien,” the “Alien Blue” features a sock-like cream-colored Primeknit base with a contrasting grey digi-camo-like pattern woven into the fabric. Perforations on both sides of the shoe allows for constant airflow. Despite its sock-like construction, a traditional lacing system is incorporated within the flexible knit upper for a lockdown fit. Underfoot, an icy Alien Blue colored Boost midsole completes the look.
