I own 3 pairs of crocs, and they are all more comfortable than I thought possible. With a liner, this version makes it a good winter shoe, still impervious to wet sidewalks but with added warmth. My only negative comment is the smell that accompanied this one (not with my others), probably coming from the fleece (petroleum product) lining.  I had to let them sit outside for a solid week to get rid of that chemical smell. (again, this has not happened with other crocs I own, so I do think it's the lining).  Still, this is a SUPER comfortable shoe, highly recommended for those who are on their feet all day.
