adidas Ultraboost 21
The all-new adidas Ultraboost 21 makes its debut in a simple yet flashy white based colour scheme with black Three Stripes branding on the sides and vibrant neon yellow hits on the Primeknit upper. In comparison to the Ultraboost 20, the new silhouette adds 6% more Boost cushioning and a new Torsion system that yields a 15% increase in forefoot stiffness for a more responsive run. The breathable Primeknit upper also arrives with Primeblue construction featuring recycled Parley Ocean Plastic.
