The ZoomX Vaporfly Next Percent 3 updates a modern race day giant, with increased ZoomX power underfoot you get even more energy return transferred to each stride. The full-length carbon fibre flyplate helps to give that stiff and propulsive feel you need for serious speed down the home straight. A bulging midsole allows the weight to be balanced for a more stable ride while a new, more breathable upper is engineered for support and performance. New, light padding on the tongue helps reduce lace pressure on the top of your foot. A complete redesign of the outsole allows a much thinner design without sacrificing durability, this helps reduce weight, and lets Nike squeeze in more ZoomX propulsion to the stack height.
