The Mach 4 running sneaker is designed for logging long miles. This everyday trainer delivers a lively ride and an energetic underfoot feel that is unquestionable Hoka. Softer and bouncier than the previous iteration, the Mach 4 employs a harmonious blend of foams - merging an incredibly soft, lightweight foam on top with rubberized foam directly beneath. This up-tempo shoe has been crafted with a new pull tab, revamped upper made from heat-pressed TPU embroidered yarns and a refined collar shape that alleviates pressure on the Achilles. Light, fast, and unquestionably responsive, the Mach 4 delivers a daily dose of speed.
