I just got back from a week in Teddy Roosevelt Nat'l Park- The Clark's were up to the challenge, no "new shoes" break in- they feel like you've had them for years right out of the box. While not a hiking boot, my boots did all the hiking and climbing  I was up for, they got muddy, wet, dirty, and after cleaning multiple times still look new. I only packed the desert boots and running shoes. { it is no fun running in Clark's} . My only issue with Clark's is their sizing- they are cut long, mine are a full size smaller than any of my other shoes. I really like these boots and would recommend them to anyone
