Give your run an ultralight upgrade in the new HOKA ONE ONE Mach 4. Taking inspiration from HOKArsquos Carbon X and Rocket X models, the Mach 4 is built for everyday speed. Using a cushioned ProFly midsole, the Mach 4 delivers lightweight support and responsive take-offs. The internal meta-rocker promotes quick transitions and a smooth ride. The soft midsole foam is supported by a rubberized EVA outsole for the added traction you need without adding the overall weight of the shoe. A re-imagined upper mesh is made from heat-pressed TPU yarn that provides structured support while remaining flexible and weightless. The upper works with a refined collar shape that alleviates pressure from the Achilles and creates a robust pull tab that makes for easy wear. Lightweight construction means unfailing responsiveness in the new HOKA Mach 4.
