These are the best slippers ever!  They are so comfortable and warm.  I am a perfect size 8 and they fit like a glove.  As others have said they are a little stiff around the opening and difficult to get on (they are not slip on and go slippers), but they do stretch out slightly so they aren't as difficult to get on as they are the first time.  I work from home so I wear them all day long.  I seriously forget that I have these on and start to wear them on the go (I'm tempted to buy another pair to wear for running errands).  These are my first pair of Keen shoes, and I love them so much that I had to buy another keen shoe so I bought a pair of their boots too.
