I love Keen but never owned a pair of their boots.  These looked comfortable, along with being warm and waterproof.  They're perfect for casual wear and definitely work appropriate.  I recieved them in the mail yesterday and presently wearing them with a casual dress, they look adorable.  More importantly they are true to size and SO comfortable.  I feel as though I'm wearing sneakers!  I don't see there being a breaking in period either as the leather is not stiff.  The boots have a lot of give and cushion.  Keen is worth the price tag in my opinion.  The seller was great also b/c I changed the size after my order was placed and everything was correct when the came.
