Dropping as part of the NCAA Pack, the adidas UltraBoost 21 ‘Louisville’ pays tribute to the Cardinals, featuring a white and red Primeknit upper with contrasting black accents on the heel counter and molded three-stripes. The sustainable build, made in part with recycled Parley Ocean Plastic, sits on a full-length Boost midsole. Overt nods to the University of Louisville take the form of a ‘L1C4’ graphic on the right sockliner — shorthand for ‘Louisville First, Cards Forever’ — and a woven heel tag marked with dual adidas and ‘L’ branding. Mismatched chenille tongue tags display a standard adidas logo on the right shoe and the cardinal bird on the left.
