Sounds like your foot is not especially voluminous. Not that it is especially low volume either, but barrie is most conducive to high volume feet (at least in D width). I would follow the conventional barrie downsizing advice. Great thing about CXL is that if your pinky toe is cramped, the leather will stretch and mold to accommodate. Sorry if that rules out this opportunity for you, but its better than spending money on shoes that are too big.
