Wow! Thank you to all for the suggestions and advice.
Oh yeah. I was totally thrown off by that ADK story.
I heard a complaint by a Limmer wearer that the "Lightweight" sole (a Vibram) was too stiff and slippery, an opinion I found to be pretty severe once I had gotten out there on my pair. I just now had them re-soled, and while I did switch to the heaviest, most-durable option (you can only re-sole so many times), I haven't had any complaints for traction, and have seen others take spills which I avoided in identical foot-placements (preceded a partner up the Beaver Brook trail and warned him about the mossy stones.., just as he wiped out).
I am now also on my sixth month of breaking in a new pair (Standards) and will put them to their first hard use this weekend.
The guys at the shop can apply a variety of grippy soles, as long as it's a Norwegian welt. Glued shoes are one-timers, but would maybe be preferable for a dry Huntington Ravine.
Before I got good boots, I made do with some old-school Doc Martens (from before they went to China): plenty of ribbing from the thru-hikers, but they had incredible grip! They just can't take the abuse. Thru-hikers, that is.
Another friend likes his Salomons, too, and my wife LOVES her Merrell's.
Good luck, and please further describe your actual slippage anecdotes!
