In reply to indigo:
Same - I'm a 43 in Katana, Kataki, Miura, Miura VS (and 42.5 in Futura and Python slippers). One thing to possibly be aware of, if you are buying without trying, is that they have a stiff band that wraps around the back of the heel. It pressed unpleasantly into my achilles and made them pretty painful until it softened.
