I purchased these shoes for my mom who lives in a country with very cold winters and much snow. She wears them in
-4F and says they keep her foot warm and dry. She is very happy with this gift. However, be careful with a size. My mom wears European size 7,5 and 8 (it depends on a brand). After reading some reviews, I bought for her size 8 (American). When I tried them on, it seemed that they were small as for size 8. So I changed them to size 8,5 (American size listed on Amazon for these shoes). My mom says that 8,5 is biggish for her but if she wears the thick socks they fit well. I wish I left size 8 instead of 8,5. But still she loves them a lot.
