When I am working from home my dress is somewhat dressed-down, especially on my feet. I like the freedom of not having to wear shoes. My circulation isn’t great though and if I wear nothing on my feet they soon get cold. Once they are cold it take hours to warm them up.
Nice warm socks are a real blessing. Once my feet are warm I’m warm.
Socks seem to have come a long way in recent years with new fibres that make your feet warm without making them smelly, for this I am also grateful.
