Just the right amount of warmth. Easy on/off but not quite wanting to falling off and I have slim feet. Would have given 5 stars instead of 4.5 but don't like the insoles that come with them... they're very stiff and have too much heel lift. I like a neutral or minimal offset and these are definitely not that...a little surprising given they're slippers not walking shoes. But... that's the beauty of a removable insole design, you can put whatever you like in there and love your slippers... that's what I did. Highly recommend these.
