This design nods to our human pacers who inspire through connection. A ticker graphic on the Swoosh logos and upper material gives you that on-pace/off-pace read. The green is in the front and the red in the back to imitate being on or off pace. More Bounce Newly implemented ZoomX foam in the midsole takes an already respected, trusted shoe to another performance level that wasn't present in the Zoom Fly 4. The addition makes for a lighter, more responsive cushioning system. Take advantage of these all-purpose traits that help you run easier, faster and have more fun on your runs. Stability Where You Need It Both the forefoot and heel offer slightly wider bases for a stable platform, so you can tackle turns and long runs with confidence. Stay in Rhythm Full-length articulated plate delivers a propulsive sensation and a smooth transition at various paces. The plate provides a sort of roll-forward feel that makes you want to take on the next step. Lightweight mesh provides for a softer, more breathable feel that conforms to your foot. Dynamic lace-up fit and supportive containment in the midfoot wrap around your foot for a contoured and secure fit.
