Smooth pink granite (when wet) is something to respect as well. Wet logs? Good luck w/that. Wood sensing studs would be cool eh?  [smiley=thumbup.gif]

The problem with thick hard soles is you can't feel what you're stepping on and the sole can't wrap the surface.

The problem with really soft rubber soles (and maybe felt?) is sticks will puncture the sole. That's happened to me twice. Once w/ tennies n once w/ Tevas - real wake up calls for me. Never wore either of those or anything like 'em on a trip since the second time.

The soles of my boots are 1/8" (maybe 3/16") thick and I often go w/o the insoles. The tread depth is 1/16". I feel they give me the best footing I've found plus they don't rip up the campsites as much and they're lighter. They are very puncture resistant as I've tested them. The big drawback with them is they're not made anymore.
