Brand new with box! Never worn!The Vaporfly 4 is a mile-eating machine that just got lighter. We trimmed weight with a carbon fiber Flyplate and ultra-responsive ZoomX foam midsole to give you race-day speed without sacrificing performance. The result is a fine-tuned racing shoe that’s trusted from the mile to the marathon.Full SpeedThe 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 propulsive feel on race day.Lighter FoamNike ZoomX, our most responsive foam, just got lighter. Running from heel to toe, it unlocks even more energy return than before thanks to a slight midsole reduction, giving you a bouncy, feathery feel.Less WeightEngineered mesh on the upper offers improved lightweight comfort while supplying a more consistent fit. We reduced the size of the heel and tongue to save even more weight.Light FeelThe midsole bulge at the heel helps reduce weight on the inside of the foot and give you a more stable ride. We reduced the weight of the outsole by using a thinner rubber compared to the Vaporfly 3.What's New About the Vaporfly 4?We made minor tweaks so you can enjoy major gains.
