The translucent monofilament window is woven into the upper, and the sock-like construction provides a snug fit and allows you to wear with or without laces. YEEZY BOOST 380 elevates the cushioning experience with a reengineered midsole that provides optimal comfort where consumers need it most. The herringbone rubber outsole offers unique design cues and improved traction.
