These slippers are super warm and are obviously well made, my only issue is that they are pretty snug. This probably helps in keeping my feet warmer, but makes them harder to put on. They don't squish my feet, but are just snug. I would almost say they run about a half size small, but more in width and just a little in the length. I do use these outside quite a bit and they haven't gotten me wet yet, but I think a sturdier sole would have been awesome. But then that might be asking a little too much of a slipper!!
