As part of the NCAA Pack, the adidas UltraBoost 21 is introduced with vibrant accents as a tribute to 'The U.' The white Primeknit upper of the shoe incorporates Recycled Parley Ocean Plastic and is complemented by orange three-stripes and a molded green heel counter. The heel features a woven tag that proudly displays both the adidas and 'U' logos, while the tongue tags are uniquely designed with mismatched chenille embellishments, featuring the adidas logo and Sebastian the Ibis. Adding to its individuality, the right sockliner boldly showcases the phrase 'It's all about the U.' Along with its stylish appearance, the UltraBoost 21 offers remarkable performance attributes including a Boost midsole, a Continental rubber outsole, and adidas' LEP system which enhances responsiveness.
