I used these for hiking in Yellowstone in June... First I wore them 'around town' to break them in.
They really didn't need break-in time, though.  Really really comfortable.
I know when I get a good pair of walking shoes~~when I do not have to 'think'  about how my feet feel while I am walking.
That's what these shoes are like.
I own about  4 pairs of Keens now--different styles--and I just ordered a pair of Winthrop Keen boots online.
I am a Keen fanatic now....
