These clogs seem to be well made, and they are nice looking. sadly, I needed to return the clogs, as they did not fit. I ordered a size 41, which according to the size chart is the correct size to order.. However, the clogs were just too big al the way through the main part of the clog, though the length was fine. I knew if I went down a size, that my big toes would then be hitting the end of the clogs. The clogs seemed to have adequate arch support.
I will say, in fairness to these clogs, that I generally have difficulty finding shoes that fit my picky feet correctly.
