The Nike ZoomX VaporFly Next% 4 'Prototype' presents a versatile racing shoe designed for distances ranging from 5K to full marathons. Off-white engineered mesh is utilized on the upper, featuring a smaller heel and tongue for reduced weight. On the lateral side, an oversized black Swoosh extends into an exaggerated midsole built with responsive ZoomX foam. A full-length carbon fiber Flyplate is updated with a higher angle compared to the Vaporfly 3, and combines with a lower heel-to-toe drop for a propulsive sensation.
