The adidas Yeezy Boost 380 Alien Blue utilizes a flexible Primeknit upper in a subtle blend of cream and grey hues. A fluorescent shade of green distinguishes the monofilament window that’s woven into the side panel, improving the shoe’s breathability while adding a see-through design element to the sock-like build. No-tie laces and a stretchy knit collar allow for easy on and off. The sneaker is mounted on a full-length Boost midsole, wrapped in a blue-tinged rubber cage and supported underfoot by a herringbone-traction outsole.
