I have 2 basic requirements for slippers.

1. They need to stay comfortably on my feet
2. They need to keep my feet warm

These slippers meet my needs better than most.

I have narrow-ish feet that are very particular about fit. The Keen Howser slippers fit my feet reasonably well. I don't have to scuff my feet when I walk just to keep my slippers on. I don't have to wear socks with them either; no pinching, rubbing or stabbing. I also didn't notice any problems with them fitting too tight initially.

I haven't had the chance to try them out in much snow yet, but I've worn them in plenty of rain and sleet taking the dog outside, and my feet have stayed warm and dry.

Overall, they're good quality slippers that fit comfortably and keep my feet warm. I'm happy with that.
