I wear an 8.5 and ordered a nine based on other feedback. They were so small I literally could not even walk around in them, I'd say these size 9 were a 7 or maybe 7.5 in US sizes. No matter how much bigger I order shoes or clothing, they are always way too small if the vendor is from Asia. Yes, I am using their size charts. Every time I have to send the items back for a refund.
