I always vacillate between 38 and 39 depending on the company. Last time I bought these shoes (in brown) in size 39. In the beginning everything was fine, then they have expanded and gelatscht so I could put them on only in the garden. That is why now buy in size 38 - they fit well, a little tight, but I know after wearing twice they already anpassen.Die blue color is not as intense, before acting powdery.
