The sneaker that spearheaded Yeezy's shift from a sleek, minimalist look to a hefty, 90s-inspired one was the Yeezy 700 Boost Wave Runner. This sneaker served as a transitional model between knit runners such as the 350 and the gritty skate aesthetic of the 550. The upper of the Yeezy 700 Wave Runner is made of grey mesh and leather, with teal mesh underlays and black suede overlays. The design is finished at the base with a thick Boost sole and striking orange accents.
