First we ordered the shoes in the same size as the foot goes down. (45). But this fell on the instep of very small and did not fit. With a high instep or wide foot a number should be ordered one size larger. Returning the first pair was smooth, the 2nd pair in size 47/48 (in size 45/46 my husband) now fit einwandfrei.Verarbeitung and quality are impeccable
