I'm on my second pair of these as I wore the sole off the first pair wearing them day and night for a couple of years.  I don't think I'll ever wear anything else.  They have great arch support so I don't even have to put my usual supports in.  Lots of toe room and great for hiking.  No more stubbed toes thanks to the rubber bumper.  And they kept my feet warm and dry through rain and snow.  No breaking in period either!  I own the Keen Newport sandals also and love them as well!
