The adidas Ultra Boost is so intricately constructed, with its use of Primeknit, full-length Boost, and the caging system. Modifications made to the Ultra Boost 3.0–the most notable being a thicker woven upper for extra comfort–took the model to new heights. Therefor, luxury versions of the newest Ultra Boost silhouette like this Heather Grey colorway are bound to turn heads. Suede covers the Three Stripes branding on the side caging, while the heel cage is outfitted in Khaki-colored leather. The rest of the upper sports the greyscale look. A white Boost midsole and a black outsole complete the design.
