I wear a size 9 and it fits snugly, but is said to loosen up when broken in a bit.  Appears to be well constructed and is warm!  The sole is not too thickened one can feel the floor beneath you. I'm hoping the stitching will hold up well, it appears to be strong.  It is as it appears in the advertisement and is IMO light weight.  I'm happy with the purchase, I wanted a slipper that would keep my feet warm for indoor use and perhaps occasional trip to the mailbox.
