I wear boots all winter but need something that I can work comfortably in and go outside to get wood or shovel snow and be warm.  These were comfortable the minute I put them on.  I love Keen but I expected a day or so of discomfort.  But nooo!  They were comfortable from the get go.  My feet are warm but not too warm.  I've been inside and out with them.  They are great and very cute.
