The Nike Air Zoom Alphafly Next% 2 is designed for runners who want to get the most out of their training and competitions and want to cover many kilometers at a high pace. Besides being a successful marathon shoe, the Air Zoom Alphafly Next% is also ideal for longer runs at a higher pace. Take your performance to the next level with this competition shoe! Midsole The shoe is equipped with ZoomX foam, which is Nike's lightest foam with the most energy return. By widening the sole, Nike has been able to add even more foam and also create a stable base. The ZoomX midsole effectively absorbs vibrations that occur during running, reducing the impact on your muscles. Moreover, you get a lot of energy back with every step, which makes running at a higher pace feel easier. Two visible Zoom Air units have been added under the forefoot. And underneath the Zoom Air Units is a layer of ZoomX foam for extra energy return under the forefoot. The Zoom Air Units are filled with air pressure and provide a light feeling while running. Between the layers of ZoomX foam and the Zoom Air Units there is a Flyplate that gives the shoe extra stability, but also forward propulsion. Upper The upper of the shoe is made of AtomKnit 2.0. The material is woven more tightly around the midfoot to provide support, while the forefoot is made flexible and breathable. The difference with Flyknit is that the material is even thinner to reduce weight. Outsole While running, the shoe offers good grip and traction thanks to the rubber outsole. Slip on the Nike Air Zoom Alphafly Next% 2 and feel how every step brings you closer to the finish line, with maximum grip, optimal cushioning and a lightweight design.
