I usually wear out socks in the toes, but these socks seem to always fit my size 10.5 feet with a little extra in the toes. My wife noticed how small the socks are after being washed and dried and tried a pair on her petite size 5 feet. They fit and she loves them! How is that possible? We both love these socks and they truly are like magic. The intricate sewing that obviously is involved, the soft cotton, and extra cush where needed make these socks head and sock above all the rest! For the first time, a 10 star rating, oops, I see only 5 stars; that'll have to suffice. I've only worn these in the cold season so far, so I hope that they aren't too warm when it's a 100 degrees outside. Did I mention how cool they look?
