I always have cold feet and bought these thinking I was getting the knee highs. I was disappointed to realize I bought ankle socks by mistake. But they were still a good purchase. The inside is really soft and keeps my feet warm. And the socks are surprisingly thin so you can wear them in shoes without adding bulk or making your shoes feel tight. My only gripe would be that there are loose threads inside that can be annoying. Might need to cut them but I don't want the seams to unravel if I do.
