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 thanks to a slight midsole reduction, giving you a bouncy, feathery feel.
• Less Weight. Engineered mesh on the upper offers improved comfort and a disappearing feel on your foot. It helps reduce the weight of the shoe while supplying a more consistent fit. And we reduced the size of the heel and tongue, saving you even more weight on your run.
• Light Feel. See how the midsole bulges out by the heel? We designed it that way 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. You still get the same reliability, just without any unnecessary thickness.
• What's New About the Vaporfly 4? We took a race car approach when updating the Vaporfly 4, making minor tweaks so you can enjoy major gains. We trimmed inessential weight in the upper, midsole and outsole without sacrificing performance.
