As soon as it arrived, I ran 7km with it. It's really very responsive and cool, quite breathable too. The foam on the sole isn't that soft, but I can confirm that you'll increase your pace. I say this to runners who are already used to it; I believe beginners should choose this model after gaining experience in running because this shoe requires speed. The faster you run, the faster you feel you're running. Another important point is that during the flat terrain run, I felt less fatigue; it really saves energy. The next step now is to run a longer distance on asphalt to see how it responds. In summary, it was worth the price paid for this Irunsvan tennis shoe, yes I recommend it based on my observations.
