All over the place
These are the really high quality loafers I've been lusting after … the soles are the thickness that so many other shoemakers seem to think women's shoes (feet!) don't need or deserve --- in no way clunky looking. The leather is also of a very high quality (yes, I get my nose involved in my shoe judgement … these have hat quality leather smell!).
They are a bit narrow in the front for my wider foot, but close enough that I have taken them to shoemaker for professional stretching.
