I purchased these boots to replace a pair of boots from the "Australian Boot Company" that I have had for 15+ years. Although this boot is not as soft nor does it have a thick insole like my old pair, the quality and style for the price was good. I use these boots as indoor slippers so yes they keep my feet warm for that purpose. I would recommend these boots as an indoor slipper. Because I do not wear them out of doors I cannot say how good they would be in cold weather.
