Query: best thing ever for winter

I love these socks!! I am so happy with these Fox River socks because they are warm, comfy and they come in my size (6.5 shoe size). Having the right size woman's sock is important, because most other socks heel ride up my calf. These socks are perfect with casual pants and jeans. they reach about 1/2 way to my knee, so they overlap well in cold weather with silky longjohn pants under my jeans. These socks are so warm and soft that my feet feel instantly warm with them on. I sleep in these socks in wintertime as well.
