I needed a rubber boot that I could wear without having to put on socks.  These are perfect.  The lining is very soft.  The entire boot is lined with this "fur", even the part under the insole.  They do run a bit small, not a big deal for me since I don't wear socks in them anyway, but if you're planning on putting on your thick wool socks first, order a size up.  The tread is decent, not so deep that they become giant mud magnets and not so smooth that I'm slipping and sliding around in the mud.  They are not too snug around my giant calves, I can still cram the hem of my jeans in there to keep my pants clean.  Overall, they are exactly what I was looking for.
