Ultraboost

Whether it’s a city street, an indoor track, or a muddy forest trail, creators know that the right running shoes can make all the difference in achieving your running goals. Ultraboost helps you unlock that best-run-ever feeling with a sock-like fit and the energy-returning edge of Boost technology.
ULTRABOOST INNOVATIONS
Ultraboost 2019 was 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. Motion weave construction through the midfoot feels like a second skin, made of fused yarn that offers the perfect balance of support and flexibility. A new fusion method 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. Finally, a re-engineered midsole enhances Boost with a 20% increase in energy return to fuel your run.
ADIDAS ARCHIVE: BOOST
Decades of research and development have fueled the quest to create the perfect midsole material. 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.
