Although a plethora of colorways have been confirmed for the silhouette’s targeted release date on February 4th, the adidas Ultraboost 21 has trickled out a bit early in this clean and simple colorway of monochromatic grey. The upper Primeknit and exterior cage/heel exoskeleton are all tinted with a classic grey hue for a no-frills, all-running approach to performance style. The redesigned BOOST sole, which has been re-engineered to have a wider, thicker rear and a rocker-like shape for toe-to-heel movement, appears in standard white.
Again, the Ultraboost 21 will be launching in several colorways on 2/4, but this grey pair of the new Ultra Boost is available now at the retailers listed below.
