Query: Incredible

I bought these slippers based on the high reviews that they were given on Amazon and other sites. These slippers did not disappoint. My feet are incredibly warm and snug. They do have a stiff sole, but that is exactly what I was looking for. Very comfortable overall. Just disappointed that they don't work for the corporate office environment, otherwise these would never come off my feet.
