These are very comfy slippers to wear all day. I live in a very cold mountain climate, in a home with wood floors. My arches are well-supported, and I love that I can easily slip these on and off as needed. Plus it makes me smile every time I see this beautiful green on my feet. The only reason I've given 4 instead of 5 stars is that they do not seem to run true to size. I wear a size 9 (I have several other pairs of Keens), but these slippers are a little big. I had planned to wear them with fuzzy socks, so it works out okay for me regardless. But if you want to wear them on your bare feet or with thin socks, I suggest you order a half size down. With thicker socks on, they stay on my feet even with me going up and down the stairs many times a day.
