Nice! Shoot me a PM if you ever come back that way.
Thanks for the advice guys, this was very helpful.
I would go with the 43.5. In my experience, my Vass shoes have all become less tight over time. This is just personal, anecdotal experience. My suede have not expanded, but the leather ones have, slightly. If they feel a bit tight, try wearing some thinner socks as well. That always makes a world of difference for me.
And for the final question... what color for the Casentino
I agree with this advice. I purchased a Budapester that pinched my feet for a while. They were definitely snug.The seller, who brought Vass to the States several years ago, told me not to worry, that they will be comfortable in time. He was right. Of course, that is just my experience. But I'd say if the shoes are not impossibly tight, they should work for you eventually.
