Very very happy with the performance and durability of this shoe. I've been using it for everything! Hiking, mountain biking (moderate downhill/freeriding and xc) and I've even lead a few easier (5.7) climbs in these things. The rubber is super grippy! I was amazed when I first put them on, very tacky. The shoe itself provides lots of support, I wouldn't hesitate to do a little backpacking with these. AND I didn't even notice a break-in time.
