My new boots[emoji7] I bought them in a 38 and they fit perfectly. In Chloe flats I have both sizes 38.5 and 39 that fit great. My feet are more narrow than average though.
I am often 8 or 8.5 US in most brands if that helps anyone. My adidas Stan smiths are 7.5 US , Sam Edelman Louie booties are 7.5 , ASICS running shoes 8.5 , everlane pointed flats 8.5
I think these boots are a classic now.
