The Vaporfly 4 is a mile-eating machine that just got lighter and brighter. We trimmed weight all over from the previous iteration without sacrificing performance. And the carbon-fibre Flyplate and ultra-responsive ZoomX foam midsole combine to give you race-day speed. The result is a more fine-tuned racing shoe that's trusted from the mile to the marathon. Full Speed:The full-length carbon-fibre Flyplate has a higher angle than the Vaporfly 3 and is combined 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 with a slight midsole reduction, giving you a bouncy, feathery feel.,Lighter upper:The 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 midsole and outsole:The midsole bulges at the heel to help reduce weight on the inside of the foot to give you a more stable ride. We reduced the weight of the outsole by using a thinner rubber compared with the Vaporfly 3. What's new?: Lighter upper, midsole and outsole. Higher plate angle. Lower heel-to-toe drop
