In reply to bpmclimb:
I'm in the same position as you, my Chameleons have no grip left on the bottom and the uppers are shot. They've been relegated to gardening shoes.
My Camp 4s are great scrambling/summer walking shoes but the soles have pretty much worn down in a relatively quick period of time. The penalty of good grip I guess. They do feel quite clumpy, the heel box is pretty massive, designed IIRC for lots of jumaring up El Cap. However I've found them to be a good compromise and would consider another pair.
Having recently tried on some Salewa mountaineering boots I'm going to have a look at the Salewa Firetail. Don't fancy the Guide Tennie (dotty rubber sole will probably be poor on wet grass/mud)
I'd be interested to hear what you go for.
