In September 2019, adidas collaborated with Pharrell Williams, a renowned music mogul, to launch a limited edition collection called Crazy BYW X. The standout feature of this particular design is its vibrant Bright Yellow mesh and knit upper, which is further enhanced by eye-catching fluorescent accents and flecked laces. The medial side of the shoe showcases Three-Stripes webbing, adding to its unique appeal. A distinct touch is added through the text-printed tongue overlays that draw attention to Pharrell Williams' humanist beliefs. As for performance, the Crazy BYW X incorporates modular Boost cushioning and a semi-translucent rubber outsole, providing optimal energy return and stability during physical activities.
