Sorel slippers are the best.  They have enough support underfoot without feeling like clunky shoes.  They are super warm without making my feet sweat.  But this pair was very large on me - so much that my heel slpped in and out of the slipper as I walked.  Sadly, I had to send them back and there is nothing available in the next size down.  But if you can find your correct size, you'll love these.
