Built with a carbon-infused nylon plate inspired by the VaporFly 4%—our most efficient marathon shoe ever—the Nike Zoom Fly Men's Running Shoe is the perfect response to the demands of your toughest tempo runs, long runs and race days. Powerful, Propulsive Feel A full-length, carbon-infused nylon plate within the midsole feels like it propels you forwards with every step, so you' re just that much closer to your goals. Smooth, Responsive Ride Lunarlon cushioning combines soft and firm foam for a balance of shock absorption, stability and response, without sacrificing comfort. Lightweight Support Nearly seamless Flymesh in the upper is designed to be more breathable through the top of your foot to help keep it cool as your run heats up. Ultralight Flywire cables hug your foot the more you tighten your laces, providing a secure fit that moves with you.
