Nike Men。The lightest Vaporfly ever combines ZoomX foam with a new full-length carbon fiber Flyplate geometry—a fast, versatile racing shoe built for distances from the 5K to the marathon. These race-day rockets have been meticulously refined to create Nike\'s most efficient speed machine yet. From the mile to the marathon, you\'ll experience unprecedented lightness and responsiveness with every stride. By trimming weight throughout while maintaining the technology that matters most, the Vaporfly 4 delivers the perfect balance of featherweight construction and powerful propulsion that racers will love. Details: • Upper: The redesigned engineered mesh upper significantly reduces weight while providing a more consistent, secure fit throughout your race. A streamlined heel counter and minimalist tongue shed unnecessary grams without compromising comfort, keeping you focused solely on your performance when it counts most. • Midsole: The full-length carbon fiber Flyplate features a higher angle than its predecessor, working with the reduced 6 mm drop to create an incredibly propulsive feel. The lighter ZoomX foam runs from heel to toe, unlocking even more energy return with each stride, while the specially designed heel bulge enhances stability when you\'re pushing your limits. • Outsole: Thin rubber strategically placed on the outsole further reduces weight without sacrificing the durability or traction you need for race day performance.
