Fast feels different in the HOKA Mach X 3. Bringing the perfect balance of firm responsiveness and reliable comfort, the Mach X 3 combines PEBA midsole foam with a PEBAX plate to create a ride that comes alive once you start moving. The result is a versatile shoe that lets you focus on what matters most—hitting your paces and enjoying every step. In our HOKA Mach X 3 review, run tester Kate said "These shoes feel peppy and fun to run in!" Details: Upper: The new warp-knit construction feels softer and more breathable than previous versions, while the redesigned heel collar is padded and flares away from your achilles to eliminate rubbing. The secure lacing system includes an extra eyelet to help prevent heel slippage, and the durable mesh upper stands up to whatever your training throws at it. Midsole: The firm PEBA foam paired with a PEBAX plate creates that responsive, propulsive sensation that makes uptempo efforts feel effortless. Combined with HOKA's signature rocker construction, every stride feels smooth and controlled whether you're cruising through easy miles or hitting threshold pace. Outsole: Rubber in high-wear areas and cutouts for weight reduction give you reliable traction and durability for daily training and speed work.
