The Yeezy Boost 700 “Wash Orange” is an October 2021 release of Kanye West’s retro-modern signature shoe in a colorway based loosely on the model’s original “Wave Runner” look. The “Wash Orange” joins a long line of Yeezy Boost 700s in featuring an orange-colored Boost cushioned midsole, and mirrors the original “Wave Runner” colorway’s use of ‘90s-inspired colors. A combination of grey mesh, suede, and leather appears on the base and overlays, respectively. The neutral look is contrasted with forest green mesh on the toe and black felt overlays on the toe and forefoot. A turquoise mesh panel is found on the toe. Contrasting grey suede surrounds the design. Underfoot, a Wash Orange-colored midsole that houses yeezy’s proprietary Boost cushioning technology completes the look. Release date: October 16, 2021
