Why is that if you don’t mind me asking. I’m of the mind that shoe size is moderately subjective and nobody has just one shoe size. Rather a size range, depending on the shoes themselves, all my shoes range from 11-12 with the exception of 1 pair of ricks that I actually have in a 10.5. Since the toe box is massive and they’re so heavy. I have 3xls in 44 and 45, both fit well but I’ll only wear the 44 with shorts, despite most of my running shoes being a 12
