We offer a wide variety of running shoes. Each shoe has its own characteristics. Then how to know what is the difference between various models? To help you out, 21RUN presents the Our Expert’s Opinion column. This column helps you get a better insight into the different characteristics of specific running shoe models and helps you find your perfect pair.
In the Our Expert’s Opinion column our running experts rate shoe models on a number of decisive elements. Do you already know which characteristics your new running shoes should have? Use Our Expert’s Opinion to check if the model you’re looking at meets your demands.
The degree of pronation indicates the extent to which a model provides support for overpronating runners. If the highlighted bar is on the far right, the model gives a high degree of correction. If the highlighted bar is on the far left, the model does not correct. Neutral runners don’t need a correction, overpronating runners often do need a certain degree of correction.
The level of support indicates to what extent the shoe supports your foot arch. The amount of support needed is closely connected to ones weight. If the highlighted bar is on the far left, the shoe provides little support, making the shoe more suitable for lighter runners. If the highlighted bar is on the far right, the shoe gives a lot of support; thereby making the shoe very suitable for heavier runners.
The level of cushioning indicates the extent to which a shoe absorbs shocks that occur during landing phase. If the highlighted bar is on the far left, the shoe provides little cushioning. When wearing running shoes that provide little cushioning, you experience a lot of ground contact and responsiveness. If the highlighted bar is on the far right, the shoe provides a lot of cushioning. When wearing shoes with a lot of cushioning you will experience a softer running feel, but less ground contact and less responsiveness.
The level of responsiveness indicates how energetic a running shoe feels. This often is also referred to as the degree of reactivity. If the highlighted bar is on the far left, the shoe is less responsive. If the highlighted bar is on the far right, the shoe is very responsive. When a shoe is responsive the energy of the landing phase is returned to you during take-off.
The Nike Air Zoom Alphafly Next% 2 is a neutral competition shoe. The Alphafly is a revolutionary running shoe made for breaking records. Elui Kipchoge became the first person ever to run the marathon under 2 hours on the prototype of the Alphafly. This is the ultimate marathon shoe due to the combination of ZoomX foam, a carbon plate and two Zoom Air Units. The Alphafly Next%2 takes energy return and a forward push to a new level.
What are the updates? Firstly, the AtomKnit 2.0 upper has been adjusted so that the midfoot is better supported and the forefoot has been given better ventilation. AtomKnit 2.0 has also been modified at the heel counter for extra comfort around the ankle. In addition, extra ZoomX foam has been added under the Zoom Air Pods for a better settlement and energy return at the forefoot. Finally, the outsole has more and thinner rubber for improved grip and durability.
The ZoomX foam is Nike's lightest foam with the most energy return. The new model of the Alphafly now has even more ZoomX foam at the heel and forefoot because the sole has been made a bit wider. The wider sole provides a stable base if you get tired during the marathon. The ZoomX midsole effectively absorbs vibrations that arise during running, reducing the impact on your muscles. In addition, 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 under 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 give a light feeling while running. Between the layers of ZoomX foam and the Zoom Air Units is a carbon plate that gives the shoe extra stability, but also a forward propulsion.
The new outsole on the forefoot is thinner and the profile has changed. The rubber has different angles in the profile for a wider grip. In addition, two rubber strips have been added to the heel so that the grip and durability also improves when you land more on the heel or midfoot.
The Alphafly Next% 2 is comparable to the adidas Adios Pro 3, Saucony Endorphin Pro 3 and the ASICS Metaspeed Sky+. These are all competition shoes made for running long distance PRs like the marathon.
