The UltraBOOST has come a long way since it made its debut in 2015 and has become one of the most forward-thinking silhouettes in the adidas arsenal. For 2021, the epochal BOOST-filled heel has been exaggerated for 6-percent increased energy return, while a new Torsion system results in a more responsive run.
The upper of the sneaker retains its PRIMEKNIT+ construction and is accompanied by PRIMEBLUE, a recycled material made of at least 50-percent Parley Ocean Plastic.
New colorways include “Crew Navy”, “Solar Yellow/Cloud White”, “Core Black/Silver Metallic”, “Core Black/Grey Four”, “Cloud White” and “Solar Yellow/Screaming Pink”, alongside the hero “Cloud White/Solar Yellow” combination.
The adidas UltraBOOST 21 is set to drop on January 28 via the adidas webstore, retailing at $180 USD.
