These shoes stink
Don't get me wrong, they're great for climbing. However, they sure smell..
The rubber is pretty sticky, and the edge is great. The heel is another gimmicky thing that's great--up to a point. It can't really preform on super technical bouldering routes. After owning these shoes for a few months, they literally smell like a small rodent crawled inside them and died. If you can stomach the smell, they're really a great bang for the buck!
