I put on the 38 and when I wore them have! it was unbearable to toe, leather quality but was certainly far too stiff and heavy and too right! I have returned but I could not recommend them in this color because there was no upper size ....
By cons I ordered the same for my daughter in turquoise leather and there was much more flexible and comfortable door and she often they are real slippers!
still a downside, the leather sole that spoils very quickly
