The Mach X 2 builds on the fast, smooth ride of the original Mach X with an increased stack height, extra PEBA foam, and an upgraded winged plate design —all in a lighter package. Inspired by the Cielo X1’s race-ready geometry, HOKA combined an extra-resilient PEBA-topped midsole and increased rocker profile for a more aggressive toe-off, complete with an extended Pebax plate for enhanced support and propulsion. “The Mach X 2 represents the next evolution of fast-paced propulsive speed training, and is ready to push any pace, whether you’re lacing up for your next workout or your next PR.” New for 2024, the Mach X 2 features more PEBA foam underfoot for additional energy return, and winglets along its full-length Pebax plate for more support and control in strategic zones. This new plate design is sandwiched between the PEBA foam top layer and a supercritical EVA bottom layer. The SCF EVA midsole includes cutouts underfoot for weight savings, while the sticky rubber zonal outsole helps maintain traction from start to finish. The redesigned upper on the Mach X 2 gives the shoe a reduced weight with increased breathability. This new lightweight woven textile is paired with a sleek gusseted tongue and race-inspired collar construction that creates a supportive fit. New reflective detailing for visibility allows runners to push the pace any time of day or night.
