"My shoes size is usually 7.5 (koreas size 245). Also I bought aldo shoes 7.5, steve madden,nine west 7. Although M size of your shoes is for people who usually were 6.5-7.5, it was a little bit big for me. After adjusting the strap, it is not perfect for me,though. But I love this shoes. I really like the color, design and confortable bottom."
