I have hardwood floor with no carpets anywhere! (my chihuahuas pee on them yikes)
So, I go through slippers like you would not believe because I wear them all the time inside the house. So far these are very very comfy and warm. I like that it has a hard sole but its not a stiff one. It makes it very convenient for going outside or running a quick errand but it still feels like a slipper to me. I normally prefer felted or leather soles, because they are soft and flexible. I don't like stiff soles because it feels like I am wearing shoes and I don't like the sound/feel of clomping around in the house on my hardwood floors. I hope they hold up for a long time, they seem to be well constructed. Very satisfied with this purchase so far. Cushioned insoles are very important to me. For work I walk about 9 miles a day (mail carrier with a walking route) and when I get home my feet ache and are tender. These seem to be well cushioned, I hope they do not compress easily.
