I've had these far too short a period of time to comment on their durability; however, I will say they seem to be a good value.  I have bought other slippers that at first appeared to be an excellent value, only to later find they fell apart quickly.  So far, so good for these - will update this when I see how long they last.  Size seems to run true, but they do need to be worn a day or two to stretch out and fit properly.
