I've accidentally worn these to the store, I forgot they were on! They nearly become ONE with my body, I love them! My house is cold and I bought them for warmth but they really are so cozy and cushioned, I could live in them all day. My feet do sweat a bit in them but with socks, they are perfect. I've put them through the washer 3 times and air dried them--they held up PERFECTLY!!! Awesome and very durable! The only negative thing...don't buy the black ones. The soles are black and WILL leave scuffs on your floor. They never look dirty but that is one drawback. :)
