Vented tongue constructions channel airflow upward

The Vaporfly 4 is a mile-eating machine that just got lighter. Nike trimmed weight all over from the previous iteration without sacrificing performance. And the carbon fiber Flyplate and ultra-responsive ZoomX foam midsole combine to give you race-day speed. The result is a more fine-tuned racing shoe thats 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, Nike's 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
Engineered mesh helps reduce the weight of the shoe while providing a more consistent fit. And Nike saved more weight by reducing the size of the heel and tongue.
Lighter Midsole and Outsole
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 to the Vaporfly 3.
What's New About the Vaporfly 4?
Nike made minor tweaks so you can enjoy major gains. We trimmed inessential weight in the upper, midsole and outsole without sacrificing performance.
