Very comfortable shoe.  I was expecting more of a slipper, but it's kind of a cross between a slipper and a shoe. It has a solid sturdy bottom like a shoe, but fleece around the shoe opening like a slipper.  I thought the inside  would be a soft cushiony material but is not. It is more of a soft plastic. I was disappointed when it came for this factor, but the shoe really is extremely comfortable. I just wear socks with them.
