my h2 be very good on a Grand Canyon river trip a couple of year ago that include maybe 20 mile of hike and a fair amount of stress of the shoe . at day 9 the stitching begin to loosen . fortunately , that be at the end of the trip . I do not consider repair they myself ; it be pretty clear stitch all over the shoe be loosen . I get a refund and would need confirmation that the manufacture of Keens have change and improve before buy any more of they .
