I have  cold feet all the time and was looking for the warmest socks available. These socks were stated as the warmest socks on other websites. They are very warm and I do like them very much but even though I am only 5'2'' and were a size 5.5 shoe the socks were too short and the heel came up on my ankle. I have found they have boot socks in the heat warmer which is what I really want them for so I will try them out. They may be longer.
