I am a waitress in a busy barbecue restaurant.  Im on my feet 6-12 hours a day.  I did not have to break in these shoes at all, and they're very comfortable.  These shoes are well made also.  I have Keen river sandals and Keen hiking boots.  I had no idea they made work shoes.  I typically go through work shoes in 6-8 months.  I hope these last!
