Train in the iconic look of IRONMAN with fresh graphics that bring bold impact to the snappy Mach 4. Designed for logging long miles, this everyday running shoe delivers a lively ride and energetic underfoot feel that is unquestionably 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 rubberised 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. HOKA Women\'s Ironman® Mach Shoes 4 in Black/White, Size 5.5
