The adidas Yeezy 450 ‘Stone Grey’ showcases eye-catching lines and a monochromatic finish. A medium shade of grey is executed on the one-piece knit upper, secured with standard lace closure and a sock-like collar. Underpinning the sneaker is a polyurethane-injected midsole that wraps up the sides, giving the shoe its one-of-a-kind aesthetic while providing structural support and stability. Underfoot, the contoured rubber outsole features a wavy traction pattern for optimal grip.
