Features:

• 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 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 we 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. They trimmed inessential weight in the upper, midsole and outsole without sacrificing performance.

Specs:
