Informed by of previous Ultraboost silhouettes like Ultraboost Uncaged where the cage support is created by internal reinforcement, Ultraboost X’s cage support is a sleeker aesthetic for women. Modern, female-specific attributes include an Adaptive Arch, which allows the Primeknit upper to mold to the foot while moving in sync with any running style. A 3D Sculpted Heel Counter is used to help the Achilles tendon to move vertically in these women’s running shoes while keeping the foot locked in place.
