I bought this in Hawaii about 5 years ago. The size is 5, which according to overseas size charts is 22cm, but I usually wear 23.5cm. I didn't feel any tightness while wearing them. I threw away the box, so I can't include it. My mother and sister also had this moccasin, so to tell them apart, I wrote an alphabet letter on the inside size label... (See photo 3) They are very comfortable to wear, and I bought three colors of moccasins! (*^^*) They can be used all year round, so I highly recommend them! Please refrain from purchasing if you are sensitive to used items. Feel free to comment. (^^)
