I love these slippers! I normally have a tough time with slippers. My feet are cold, I put them on and in 20 minutes my feet are roasting hot. I take them off and a few minutes later my feet are cold again and the whole cycle repeats. These slippers are warm and cozy but thy must breathe well because I can wear them for hours without my feet getting too hot.  The footbed is comfortable and seems to have molded itself to my feet with my high arches. They are a little tough to get on but it seams easier with time. I wear size 8 shoes and bought the size 8-9 slippers. They still fit well with just a little slipping in the back. Overall the best slippers I've owned!
