ULTRABOOST 21

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. The new Ultraboost 21 helps you unlock that best-run-ever feeling with a sock-like fit and the energy-returning edge of Boost technology. While it doesn’t carry the name Ultraboost 6.0, the UB21 is the latest evolution of the adidas Ultraboost franchise, boasting some major updates in comfort and performance over previous iterations.

ULTRABOOST INNOVATIONS

Ultraboost 2021 is 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.
