To create the Skyward X, we broke all the rules. This new cushioned training shoe takes flexibility and fluidity to the extreme and features a revolutionary suspension system that compresses and returns energy with every step thanks to a convex carbon fiber plate. A soft, highly resilient PEBA foam, placed as close as possible to the foot, provides a lively yet cushioned ride. Meanwhile, the supercritical EVA structure provides stability for racking up the miles with unprecedented ease.
