Nike Men。A light, efficient design feels propulsive for all 26.2. 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. Full Speed A full-length carbon fiber Flyplate provides a propulsive, racing feel. More Energy Return Nike ZoomX foam, our most responsive foam, just got faster. Running from heel to toe, it unlocks even more energy return than before thanks to a slight midsole reduction, giving you a bouncy feel. Engineered Mesh Engineered mesh offers improved comfort and a disappearing feel on your foot. It helps reduce the weight of the shoe while supplying a more consistent fit. Light Feel See how the midsole bulges out by the heel? We designed it that way to help reduce weight on the inside of the foot to give you a more stable ride.
