The cold weather is making my poor arthritic feet very unhappy. I have thick, fluffy socks that are great for at home but do not fit into my shoes alongside the orthotics. Has anyone found any thin thermal socks that are warm without taking up too much space in shoes? I found some walking ones but they had lines and they irritated me. (I'm a proper fuss pot.) Any pointers would be much appreciated, please and thank you.
