I normally wear US size 5.5. Since there is no half size, I ordered a pair of US size 36 equivalent of US size 5 B(M). Unfortunately, it turns out to be too big. It feels like size 6 or 6.5 to me. The back of the shoes is sitting too high and rubs my ankle in the wrong way. Style is great and it feels comfortable if I don't have to walk at all. Already sent it back today.
