Interesting, the majority of the reviews on these slippers are very positive.  I bought a pair for the winter season as a result.  I thoroughly agree on the one hand, they are very warm and cozy.  I'm a graduate student and spend a lot of time at my desk studying.  But on the other hand, the rubber sole around the heal area wore out over one winter season, and I never wore them outside, only in doors on carpeted floors.  I'm going to contact Sorel and see what they can do for me, but I rated them #2 because they wore out, and in my opinion, way too soon.
