Be confident in your weekly workout and shatter your personal best with a durable shoe that goes everywhere from your daily runs to the finish line of your favorite race. It offers comfort and reliability, but with the feel of propulsion for speed and coolness. This level of versatility is rare in the running world. But who says you can't have it all? The newly integrated ZoomX foam in the midsole takes an already reliable and well-loved shoe to a level of performance not previously seen in the Zoom Fly 4. This addition makes the cushioning system lighter and more responsive. Take advantage of these versatile features to free up your stride, gain speed and have fun during your run. The forefoot and heel are slightly wider to create a stable platform, perfect for tackling turns and long runs with confidence. The full-length articulated plate offers a propulsion feel and smooth transitions at any pace. It provides a forward rolling feel that propels you to the finish line. The upper is made of lightweight mesh for a softer, more breathable shoe that conforms to the shape of the foot. Dynamic lacing and a snug fit wrap the midfoot for a contoured, secure fit.
