great general purpose shoe
All the comments below on the sym's limitations I agree with. They are on the soft side, they don't perform as well on overhangs as others. But regardless, these shoes are awesome. They have conformed to my feet so perfectly that they feel more like climbing socks than climbing shoes. I've never had troubles with them slipping while heel hooking, I think that's more an issue with sizing than the construction of the shoe. Great second shoe for the gym, outside sport and multi-pitch.
