I think these are great shoes for walking on any terrain, with great support and a firm footing. I always feel like my foot is planted firmly on the ground stands, as stable as any hiking boot I've had, but less heavy and bulky. In my experience, it was comfortable to use all day. It's a bit small so I ordered the next size up a half size and it worked fine. I didn't hear the "whistle" that some people report when walking - maybe Merrell solved that problem? Highly recommended.
