Bought these for the wife. She is usually a 7 so I started with the 7-8 size. They were so small her heels were handing off the back. I returned them to Amazon to exchange for the 9-10 size. These were actually the correct length for a foot that always takes a 7. However, there is a band of material over the top that made them pull down very tightly on her instep making them VERY uncomfortable. So, the second pair goes back and this time the replacements will be a different brand. Would not recommend....
