I bought a pair of KSO's around July of '09 to go hiking. I've enjoyed it, but you have to be more aware of where you step as some rocks do, in fact, hurt. Also, getting things in between your toes can be an issue. I don't really find the former to be much of an issue. Being more observant of my surroundings isn't a bad thing to me. The latter can be an issue, but it's also related the former.
Overall, I'm pleased. I don't have any intention of going back to more traditional shoes.
