The Emu Stinger Lo boot is the most comfortable boot I have ever owned.  I just got them for Christmas, and they are so soft on the inside and very comfortable to walk around in.  I recently wore them on vacation, and they did not need a break-in time.  These are my shoes of choice for when it's cold.  I'm a teacher who is on my feet for at least five hours during the school day, and I have worn my Emu boots every day this week.  I recommend getting a water proof spray to put on them to keep them looking nice.  You should be able to purchase any leather or suede water proof spray for them, but remember to test it on one spot first to make sure.
