In reply to topper:
I've got a pair of the Tennies as I wanted something a bit more light weight and loads of people seem to rave about them. I really don't rate them as approach shoes. Although they are sticky, light and fairly technical after only a couple of months the sole has started to come away from the body of the shoe at the heal - build quality isn't there IMO. Also they are so light there is literally nothing to them - walking to the crag through a short streach of damp (dew) grass results in damp feet which bugs me. When these ones die (v.soon I recon) i'll be going for something a little heavier and that can handle more than a totally dry walkin along good tracks!
Previously I had the predecesor to the Camp 4, however and they were awsome - a fair bit heavier but pretty much waterproof and near indestructable managing a lot of mountain crag walkins, general wear, mountain biking and even a festival weekend.
Hopefully useful!!
