I love these boots, I haven't had them very long but they are very comfortable right out of the box.  I have owned/own several pairs of Keen's, great shoes!  I don't know why they all run a half size small though, that's just one quirk with Keen's that always perplexed me.  Also I agree with other reviewers on other sellers sights about the short laces, they come up short on this.

Other than that I highly recommend them.
