adidas unveils its biggest update to the Ultrabost with the reveal of its 2021 model. The running shoe now features 6% more Boost foam than the previous model and has an entirely new silhouette. The new design features LEP (Linear Energy Push), which adds a stiffer midsole material to reduce flexibility in the forefoot, allowing for enhanced responsiveness. It also has a new Primeknit+ upper that enhanced foot support and movement and it's constructed with their recycled Primeblue fabric that is upcycled from at least 50% Parley Ocean Plastic.
Ultraboost 21 launches on January 28th and a global launch will follow on February 4th.
