Honest for 40 euros, not more, in the two weeks that I have been wearing them only for office work and occasional walks, it seems like they will tear at the part where the fabric connects with the nose. They also bother a little at the heel. What impressed me is that half of the models have nothing to do with the photos from the four that I had chosen, only this one matched the photos, and we are talking about an official retailer. As for the size, I usually wear 44.5-45 depending on the model, and just to give you an idea, I wear 45 in Nike, 44 and 2/3 in Adidas, and 44 in Puma.
