The Finer Details A full-length carbon fiber flyplate provides a stiff and propulsive feel. Specifically selected Flyknit yarns and engineered zones in the forefoot bring a new level of performance to the Vaporfly. Ample breathability around the toes combined with soft, yet supportive yarns deliver our most customized upper for the Vaporfly. The result is a softer, cooler design that conforms to your foot. An updated thin outsole rubber uses less material without sacrificing durability, which helps reduce outsole weight and thickness. This allows for extra millimeters of ZoomX foam underfoot and a smoother transition through your stride. Light padding on the tongue helps reduce lace pressure at the top of your foot. A new Waffle outsole pattern with perforations saves weight and delivers multi-surface traction in various weather conditions. Nike Mens Vaporfly 3
