No particular tips, I guess. But I also tend to have very cold feet... at night especially. I wear fuzzy socks to bed. We live in a townhome that sits on a concrete slab, so no basement. This also tends to contribute to cold feet. During the winter I wear fur-lined boots around home (made by Minnetonka Moccasins.) (No socks.) They keep my feet toasty warm during the day. And when my feet stay warm during the day, they tend to be less cold when I do go to bed.
