I have now bought the soles already as full and as a half sole. And I vacillate between 42-43 and 44-45, because the soles fit depending on shoe. The motorcycle boots are 44 which I have then taken the size 44-45. The sole had to be cut also at the top more than 5mm. Unfortunately, the soles of this size are formed so that the supportive "bump" is a little too far forward. I would hope that the distance from the heel is measured for Fußgewolbe and indicated. The length can be easily cut when the sole would be a little longer. But unfortunately, the soles of such boots or work shoes that you choose something bigger does not always fit and you walk so just outside the Fußgewölbeunterstütznung
