adidas Ultraboost showcased the world’s first 3D-knitted running shoe, designed to flow with natural running motion and place you closer to the technology for maximum comfort and more energy return than ever before. The upper is fused with yarn containing 50% Parley ocean plastic and offers the perfect balance of support and flexibility. Fusion eliminates layers of adhesive, providing instant step in comfort and a direct connection to the seamless Primeknit upper and Boost midsole. A 3D heel frame allows for heel expansion and pressure distribution with each step.
ADIDAS ARCHIVE: BOOST
After countless trials and hundreds of iterations, the Boost midsole was launched in 2013. Created in collaboration with German chemical company BASF, Boost is comprised of thousands of foam capsules bonded together using steam. This midsole technology has set a new standard in the industry and is now featured on more than 20 silhouettes from baseball cleats to lifestyle sneakers to the unprecedented Ultraboost—the first running shoe to deliver energy return with every step.
