I've got to say that I am a backless slipper person, meaning that when I get home the first thing I do is to slip on my most comfortable foot wear.  I've owned many pairs over the years and this is one item that I do not mind paying a high price for if the comfort and warmth is there.  I've owned Uggs, and Clarks, and several off brand names - all were very good and the Uggs and Clarks were exceptional, but...the Sorel Falcon Ridge fit like a nice pair of socks, gives plenty of support, and are very warm.  They also "almost" look like a nice pair of shoes so I try to get away with wearing them even when I have company.  They are easily the best pair of backless slippers I have ever owned.  They are so good that I am tempted to buy a spare pair for the time that my current pair wears out - I don't want to risk having to "buy down" if Sorel stops making these.  For anyone who has never had a pair of backless slippers before:  try them; they are as warm as a full slipper and very easy to slip into in the dark or when your back is on the bum....and soooo comfortable.
