I bought the shoes for the hall, in the hope that he will be a good and effective successor for my Nike Free. Well, at least, it fits perfectly, is soft and flexible, and does the job just like the others. Only one hook has the whole: In comparison to the Nike Free that are super-ventilated, these are like a sauna. You sweat in it and they start after a few hours of sport to muffles. Now, after a week, they smell even more than the Nike Free for two years! But because they are of course easy compared extremely cheap, you can not bear the might.
