<ul> <li>A full-length carbon fiber Flyplate provides a stiff and propulsive feel.</li> <li>Nike ZoomX, our most responsive foam, just got a little better. Running from heel to toe, it unlocks even more energy return than before, giving you a springy, bouncy feel.</li> <li>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.</li> <li>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.</li> <li>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.</li> <li>Light padding on the tongue helps reduce lace pressure at the top of your foot.</li> <li>New Waffle outsole pattern with perforations saves weight and delivers multi-surface traction in various weather conditions.</li> <li>Offset heel seam helps reduce friction in the heel area.​</li> <li>Wider toe area for a roomier fit</li> <li>Internal foam pod at heel for extra cushioning</li> </ul>
