One major flaw for this purchaser.  Size was slightly large so that heel of foot tended to pull out when walking.  This might not have been a problem if the heel cut of the slipper was a little higher.  It was much too shallow.  This resulted in stepping on this &#34;edge&#34; when the foot heel came down.  If you're going to make a slip-on slipper I'd suggest either making it with no heel cuff at all or raising that area of the slipper so that it better cuffs the foot heel.  Sorry to have to return these.
