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.

I've always returned to ultraboost and this new iteration is even better than the last. It fit a bit tight the first day but once I got moving in it, the fit was awesome.

Very comfortable, but not a fan of the heel being so big it juts out & hits opposing ankle.
Found favorite athletic shoes for a great value!
Great shoes from Adidas. They are true to size. The black color is nice because it doesn’t show dirt, and the metallic-looking striping makes the shoes stand out. Very pleased with these shoes.
My favorite shoes i own are all UltraBoostAlways fit perfectly
The shoes were exactly as described and came very quickly. Also, good communication as the shipment progressed. Thanks for a great purchase experience.
I was unsure about this style because I had not had a chance to try them on and wow I was really impressed with the looks and comfort when I tried them on.
Great shoe, I love the boost they did a great job with earlier models, this shoe is a step up.
