Cozy on the inside, durable on the outside especially with its rubber sole ...which also adds some arch support.  Great indoor/outdoor slippers....allows you to walk on your damp lawn in the morning to get your paper without your slippers getting soaked through...or even take you dog for a quick trip around the block.  However I should have heeded the reviews and recommendations  of others and ordered the next size up.  It runs a little small and a little narrow.  I can wear a Womens size 5.5 or 6.  So I figured I should be good with a size 6.  But my feet are slightly wide and I have a bunion on my left foot.  So the 6 is a little too snug and the sides of the slipper rub and irritate the bunion on my left foot. I also think the slippers are a little short too.  Both of my heels seem to ever slightly overlap the outer edge of the back of both slippers....which makes me feel like I should have gotten the next size up for a more comfortable fit.  Unfortuntely, I wore them before realizing this.  So now I am trying to remedy the situation by attempting to stretch out the slippers with shoe stretchers.  So heed my warning and buy a size up if there is any doubt.
