So far, so great. I'm hiking in Guam and the terrain here is brutal. Thick mud, hot temperatures, wet and muggy, slick rocks, you name it, we've got it. Maybe the desert is harsher...

These guys are great. They eat up dirt and mud...just chew it up and come out very clean after the hike. Other reviews have pointed out that they aren't the most stable on slick rock and that's true, but they aren't horrible either. They would be fairly worthless on pavement. This isn't a shoe that you're going to enjoy transitioning from dirt to pavement on, especially if you're racing.

But if you want a shoe that is going to give you the maximum stability with the most comfort...this is it.
