Adidas presents their latest rendition to their signature Ultra Boost with the 4.0 silhouette ($180). This season the runner showcases a new primeknit pattern, reminiscent of the 1.0 and 3.0 models. The white upper sees a tonal white colorway, with no contrast knit detailing. The design sits atop a white boost midsole, and finished with a black continental outsole. White laces tie the model up, while chrome "Ultra Boost" branding at the heel cup give the runner a signature touch. Purchase your pair online and in-store.
