In its fourth edition, the Mach 4 take their biggest leap forward, built on themes inspired by the Rocket X and Carbon X. Designed for logging long miles, this everyday trainer 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 rubberized foam directly beneath. These podiatrist recommended shoes for overpronation are also great for flat feet. They have 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. One of the best hoka running shoes. - Mens size 11.5D - NEW IN BOX - Engineered mesh delivers breathable comfort - Anatomical Achilles construction - Removeable, molded EVA sockliner - PROFLY™ midsole gives a cushioned landing and propulsive toe-off - Early stage Meta-Rocker offers smooth ride - Rubberized EVA outsole provides lightweight ground contact and responsive cushioning
