My feet are always cold, even though I live in the South. I don't wear sandals ever, always those low sox with closed toe shoes, and I wear sox to bed at night, often taking them off during the night when my feet finally warm up. At the same time, if I've been on my feet too much during the day, I find my feet burning when I finally sit down--it's strange how they can be hot and cold at the same time! Joan
