As the next step in their innovative line of footwear, the adidas Ultraboost 21 arrives in an evolutionary new style featuring repurposed textiles, more Boost cushioning and an updated responsive design. The Ultraboost 21 is constructed with a Primeknit upper made from Primeblue
— a high performance material created with Parley Ocean Plastic, using at least 75% recycled yarn. An exaggerated heel provides extra Boost cushioning, plus a new LEP Torsion system delivers enhanced flexibility in the forefoot, for a more reactive stride. Patented Continental rubber delivers unwavering traction underfoot.
Meanwhile, adidas’ latest Ultraboost DNA pays homage to the OG Ultraboost silhouette, adding an updated Solar Yellow colourway. This runner reverts to the Ultraboost 1.0's original moulded heel unit and Primeknit upper, introducing protective no-sew overlays throughout its heel and toe. Like the Ultraboost 21, this Ultraboost DNA uses recycled Primeblue materials which reflect adidas’ move towards sustainable and eco-friendly design. A full-length Boost cushioned midsole pairs with the adidas Ultraboost DNA’s rubberized Continental outsole, delivering long-lasting comfort and traction underfoot. Both models are available online now.
