As is well known, sizes vary from company to company, but the 37 to 39 that I got, and I wear 37 to 38, fit a person who wears size 44. I think the difference was not just small, there was a deviation that is not considered reasonable. Their fit was not even like one size to say okay, my foot was swimming inside... The pleasant thing is that I managed to give them away and they didn't go to waste in the closet drawer.
