Just got back from Yosemite HALF DOME! Best camping and hiking trip ever! And this shoe is def. the best for this kind of hike. I'm a novice hiker and first time climbing the half dome. This shoe provided the ventalation, stability, light weightness, and TRACKTION that you'll need. Especially climbing up the almost 90degree slab of rock, this shoe was great in gripping the small crevases and wood blocks.
I tested the shoe out on a small run in Runyon Cannon in LA, and it was great for running down hill too! Great buy and a must buy!
