The adidas UltraBoost 21 ‘Washington’ is drawn from the NCAA Pack, a footwear collection that gives fans the opportunity to express their school pride. This pair salutes the Huskies with a white and violet Primeknit upper accented with metallic gold three-stripes. The sustainable build, made in part with recycled Parley Ocean Plastic and zero virgin polyester, rests on a full-length Boost midsole. ‘U-Dub’ is printed on the right sockliner, while purple chenille tongue tags feature mismatched adidas and ‘W’ branding. Both make repeat appearances on a woven tag affixed to the back heel.
