I bought these shoes to keep my feet warm. Our temperatures are frequently in the negative digits. These are great for slipping on to run the kids to school or the grocery store. They aren't a light shoe but I have gone shopping all day in them.  They have good soles so no slipping on the snow or ice.  I did order up a half size.  The fur lining makes them a little smaller inside and I like to wear wool socks in them when it's really cold.
