These fit well and are comfortable.  Compared to another set I bought, these have flat  inner bottoms against your soles. The other pair dipped slightly in the center and helped keep your foot from slipping sideways.  It's not really a problem, but I slightly favored the other pair. UPDATE: In less than 8 months of use, the rubber outer-sole has separated from the slipper about a third of the way back.  The rubber was not even glued to the slipper body.  The only thing holding it on is stitching around the edge with fine thread.  Between the rubber and the body is a layer of thin cardboard-like material, so it would be impossible to glue the parts back together.  These are headed for the trash.
