The Adidas by Stella McCartney Ultra Boost X is the ultimate union of high-performance sport and considered design, made for the woman who moves through the world with intention and style.

Crafted with a seamless Primeknit upper in a rich red-to-burgundy gradient, the shoe features a distinctive cage-style lacing system with woven flat laces, a branded Stella McCartney tongue tab, a deep plum heel counter, and a signature honeycomb-textured Boost midsole finished with a gum rubber outsole for grip and visual contrast.

The stretchy polyester-spandex knit upper wraps the foot like a second skin, while the full-length EVA Boost midsole delivers responsive, cloud-like cushioning that performs as beautifully as it looks.
