Nice OUTDOOR slipper. Definitely not a comfy indoor slipper. I ordered these to wear as a quick slip on to go outside during cold months. They have a have a hard sole which is great. They do not have a soft cushion inside or anything for arch support. This is why I would not recommend for indoor wear. They fit snug, but I suspect will loosen up with time. I do not like the heel rim on it. It kind of rubs and is uncomfortable, but once the slipper loosens up, I suspect it won't be an issue. Would make sure to spray an all weather protector on them first.  Would recommend.

Update: The slipper has a cloth like coating on the sole. Not sure what the purpose of it is. But after a few days it started to come off and its causing a few problems with uneven gripping. Perhaps once it comes off, it will get better. Still decent enough for outdoor use. Definitely NOT an indoor slipper and not very warm.
