Manufacturer’s Description of the Nike Vaporfly 4 (Road Racing VF)
The Vaporfly 4 is described on Nike’s site as a “lean, mean, mile-eating machine.” Compared to the Vaporfly 3, Nike trimmed weight throughout the upper, midsole, and outsole without sacrificing performance, resulting in "a lighter, more propulsive all-around racing shoe that’s trusted from the mile to the marathon."
Key features include:
Full-length carbon fiber Flyplate: Offers a dynamic, propulsive feel ideal for racing.
ZoomX foam: Nike’s most responsive cushioning; with a slightly thinner midsole, it delivers even better energy return and a bouncy ride.
Engineered mesh upper: Lightweight and comfortable, it reduces overall shoe weight while offering a secure, “disappearing” feel.
Unique heel midsole bulge design: Nike intentionally lightened the inside of the heel to enhance weight savings and promote a more stable ride.
What’s new vs. Vaporfly 3:
Lighter upper, midsole, and outsole
Higher plate angle for better forward propulsion
Lower heel-to-toe drop (6 mm)
Specs:
Men’s weight: approx. 190g (6.7oz, US M10)
Heel-to-toe drop: 6 mm
Women’s weight: approx. 152g (5.4oz, US W8)
