I had read some pretty bad reviews about the quality of these shoes. I, who wears only Caterpillar, with my flat feet is much better, I really have no complaints about this model. It is consistent with the brand. As for the size, since I only take this brand, I always take the same size and it does not fluctuate; I would not buy other shoes by mail. In my eyes the model is beautiful, it is more robust and comfortable to wear.
