My size: 8.5 (women), ordered and received 8.5 and they fit very well; I was skeptical about the height of these shoes, but they cover the ankles perfectly, perfect for holding the legs while playing tennis (which is why I bought them); I wore them at home for a few hours and forgot what they were wearing, I felt like I was walking barefoot. very convenient; They arrived very well packaged in the expected time, so I am very happy with the purchase.
