My usual shoe size is a 7-7.5 and although I wear size 6-7 in my other Crocs, I fortunately ordered these in the size 8.  They fit very well over my thick wool socks and I expect they will be very comfortable on cold days.  The rear is higher than my Classics and the edging around the shoe appears to be well sealed.  I don't look forward to wearing these, however, on snowy or wet days, as the holes at the top of the shoes which are designed for air circulation, also will allow seepage of moisture and cold air or wind.  The polyester and fleece liner is removable and washable, so if they do get wet, it's not the end of the world.  My purchase was in Mushroom/Blush, and the color is pinker than the very tan representation on this site.  My only complaint with these shoes is the smell when removed from their plastic bag which I know from experience will eventually dissipate.  Since these are clogs, the back does slip as I walk, so if you're in the market for a more encased shoe, I'd select another style.  I think these would also be an appropriate slipper for around the homestead and expect them to last as long as my other Crocs -- a very, very long time.  The shoes I received were made in Mexico.
