Everything about the Mach X Caged is extreme, from the structured TPU cage to the high-energy-return Pebax plate. The underfoot is cushioned with Super-Critical Foaming technology, while the upper features transparent mesh underlays and a futuristic injection-molded construction. No expense has been spared on performance details. The running shoe offers the ultramodern sole design of the Mach X 2 and elite-level technologies that are anything but ordinary.
