I wear an 8.5 in comfort, and 39 is usually just fine, these feel like an 8 on me as in I can stand still in them but cannot take steps without pain, not stretch to them and arrived with the sole separating from the shoe! Broken! And the emboidery has no liner in inside so it would rub against toes scratching. Cheep cheep cheep and for this cheeper price I have seen better--at least not broken. Am returning.
