The floors are very cold in our house, we're on a slab, so house slippers are a must in winter.  These slippers are super cozy and very comfortable.  I really like them.  The only thing I didn't realize about them is that they are not slip-ons and I do prefer a slip-on slipper.  However, that is a minor inconvenience, so I'm not reducing my rating for it.  The soles are very sturdy and non-slip, you could actually walk outdoors with them if you so desired (although I will not since I don't wear outside shoes in my house).  They are very well made and look like they should last for several years indoors.  Highly recommended!!
