As far as cosiness goes these slippers are amazing. I bought them as I needed more support on the sole than normal slipper boots and they are wonderful for that. They are well made and very very warm, but also very heavy. I've marked them down a couple of stars though as I had to send my original pair back as I just couldn't get them on! There was no "give" in the ankle section so I couldn't get my foot inside them. I ordered the size up and they are better but are still a struggle to get on.
