I wear a size 9 1/2 shoe.  The manufacturer calls these "Women's One Size" - but I think they are made for tiny Asian women.  The ankles hurt as are too tight, and they are too short.  I'll see if my granddaughters can wear these. I can't.  The colors and style are super cute just as the photo showsbut they are slightly shorter than crew sockssitting down you can see my ankles between the socks and my jeans.
