Just received these shoes for my husband yesterday.  He was truly thrilled with them and said they were the best shoes he's ever worn.  He put them on right away and has been like a kid.  He normally wears a 10.5 and these are a euro 43.  They ARE a tiny bit snug in the right toe, but being experienced with Birkies, we know that will adjust with wear.  The looks of this shoe is very now, but seem durable - time will tell on that issue.  The inside support is fabulous, and for him - on his feet all day, they are the best.
