With a snug, sock-like fit, the adidas Women's Ultraboost 20 Running Shoes are built for high-performance, allowing you to touchdown with control and ride with comfort.
Collaborating with the ISS U.S. National Laboratory to learn and share information, adidas has produced the latest in the range of performance-driven innovation to elevate running comfort and responsiveness to new heights. With a goal of sending Boost technology on a mission into space for microgravity testing, aiming to develop even higher levels of energy return and create the future of sports footwear performance.
Soft and stretchy Primeknit+ ensures great fit and flexibility, while stitched in Tailored Fibre Placement wraps the foot and delivers locked-in support.
Providing superior underfoot cushioning, the midsole contains 20% more Boost for an amplified feeling that returns energy to your stride with every footstrike.
An updated 3D Heel Frame features a stripped-back design that cradles the heel and holds it firmly in place for adaptable stability as you run.
