This sneaker was released after Ye, formally known as Kanye West, and adidas ended their partnership. The upper is made of breathable PrimeKnit, which creates a bootie-like fit and conforms to the foot’s shape. A semi-translucent strip of knit material runs across the side panel and allows the foot to breathe. The knit in this area is slightly looser than on other parts of the upper. A ribbed TPU cage wraps around the full-length Boost midsole. Although the TPU cage comes in Steel Gray, its texture adds contrast to the shoe’s design.
