I bought these because of the great price thinking they would be functional slippers to wear around the house. These are socks, not slippers. They are warm for the winter months, and would be too hot for summer but they constantly fall off the back of my foot because there's nothing to hold them to your feet. Also, these are not for you if you are looking for support. These feel like socks, as there is no sole or support for your feet. You feel everything under your foot and I would not wear these outside at all. It's a pain continually putting them back on after they flop off my heels.
