About this product
Releasing as part of the NCAA Pack, the adidas UltraBoost 21 ‘Kansas’ showcases a familiar color combination inspired by the Jayhawks. The grey Primeknit upper is made in part with recycled Parley Ocean Plastic and features a molded midfoot cage with royal blue three-stripes. A woven heel tag features dual adidas and KU branding, while mismatched chenille tongue tags display an adidas logo on the right shoe and the Jayhawk mascot on the left. ‘Rock Chalk’ is printed on the right sockliner in a nod to Kansas’ signature chant. The running shoe sits atop a full-length Boost midsole, supported underfoot by a Continental rubber outsole.
