The Vaporfly 4 is a mile-eating machine that just got lighter and brighter. We trimmed weight with a carbon fiber Flyplate and ultraresponsive 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 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 propulsive feel on race day. Lighter Foam Nike 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 Weight Engineered 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. Lighter Feel The midsole bulge at the heel helps reduce weight on the inside of the foot and give you a more stable ride. We also used a thinner rubber compared to the Vaporfly 3 to reduce outsole weight without sacrificing reliability.
