What Our Gearhead(R) Experts Are Saying: "The Vaporfly 4 is my go-to race shoe when I want max efficiency. It's lighter than the 3, has a higher plate angle, and just feels more responsive mile after mile. The ZoomX foam keeps my legs fresher, and the engineered mesh disappears on the foot-it's like running on air." The Nike Vaporfly 4 Racing Shoe is built for speed from the mile to the marathon. Lighter and faster than its predecessor, it trims weight across the upper, midsole, and outsole without compromising performance. At its core, a full-length carbon fiber Flyplate teams up with ZoomX foam-the most responsive foam in Nike's lineup-to deliver propulsive energy return and a smooth, racing feel that keeps us pushing from start to finish. The updated midsole geometry reduces weight on the inner foot for better stability, while a higher plate angle and lower heel-to-toe drop improve efficiency through every transition. An engineered mesh upper wraps the foot in breathable comfort with a barely-there feel, ensuring a distraction-free ride when seconds matter most. With its ultralight build, bouncy cushioning, and propulsive carbon plate, the Vaporfly 4 is a trusted choice for breaking barriers, chasing PRs, and covering long miles with speed and efficiency.
