I like these slippers, but not as much as my ll bean shearling slippers, after comparing over the past year.  The reason is that there seems to be enough man-made material in the foot bed to make my feet sweat.  The ll beans are all natural and I can wear them all day without getting the feet sweats.  I do like the sorels for going outside to the mailbox, and they look nice, but not as comfy.
