I've been wearing a half dozen pair of Keen shoes for the past year and a little more. I 've worn one pair of Newport H2's daily for general purpose and hiking. Recently I've stopped wearing them for our daily hour walks because they've become so compressed in the critical pressure points. They've have lost ability to cushion the shock of steady footfall. I'm using a new pair now for walking, the old pair for messing around the yard. Inspecting the old pair showed that I was wearing through the yellow stuff on the soles to the black. My wife's pair [purchased at the same time] show the same wear. Given our level of activity, I'd estimate near a thousand miles of walking brought them to this point. Not bad really. When I could run 30 miles a week, I'd wear out a pair of shoes in 6 months easy. I'm still sold on the product. The older I get the more fond I grow of the things that bring comfort to my days. My wife and I walk 5 or more days a week. Usually 3-5 miles sometimes 5 to 10. We go through shoes. We understand it as a cost...an investment in our health. We've worn them chest deep in water, thigh deep in muck, through sand and slop on bog and shore..they're a great all terrain amphibious warm weather, hiking sandal. If you use them expect them to wear out.
