Launching as part of the NCAA Pack, the adidas UltraBoost 21 showcases vibrant accents in a nod to ‘The U.’ Recycled Parley Ocean Plastic is integrated into the white Primeknit upper, contrasted by orange three-stripes and a molded green heel counter. A woven tag affixed to the heel displays dual adidas and ‘U’ branding, while mismatched chenille tongue tags feature an adidas logo and Sebastian the Ibis. ‘It’s all about the U’ is printed across the right sockliner. Performance benefits include a Boost midsole, a Continental rubber outsole, and adidas’ LEP system for enhanced responsiveness.
