Hi. I just got a pair. They are very wide and roomy and the footbed is great. They are beautifully made and look really robust. I normally take 38 regular in Birkenstocks and got the same in the boots, and they are a similar fit to the Arizonas. However the leather is extremely stiff, almost like cardboard. Don't expect to wear them out right away, as mine are taking 1-2 weeks to break in before that stage. Also lots of bargains on Ebay and Vinted, if you are prepared to get some that someone else has tried on. Mine were £150 ON Vinted.
