Ultralight design delivers a propulsive feel from a 10k to a marathon The Vaporfly 4 is a lean, mean, mile-eating machine. We trimmed weight in the midsole, outsole and upper from the Vaporfly 3 without sacrificing performance. The result is a lighter, more propulsive all-around racing shoe that’s trusted from the mile to the marathon. Lighter Upper Engineered mesh helps reduce the weight of the shoe while providing a more consistent fit. And we saved more weight by reducing the size of the heel and tongue. Lighter Foam Nike ZoomX, our most responsive foam, just got lighter. Running from heel to toe, it unlocks even more energy return than before with a slight midsole reduction, giving you a bouncy feel. Lighter Outsole We reduced the weight of the outsole by using a thinner rubber compared to the Vaporfly 3. Full Speed The full-length carbon fiber Flyplate has a higher angle than the Vaporfly 3 and combines with a lower heel-to-toe drop to give you a stable and propulsive feel on race day.
