100% trail runners. I had a pair of the old Vasque Breeze II (not III) which I liked a lot and used like trail runners- meaning I would run in them. But after they finally wore out last year I began looking around for a replacement (they no longer make the II, and the III is not the same boot). I ended up using trail runners. I recommend Sauconeys. You can get their basic trail runner model for around $60 and it has pretty good traction. I wear them on long approaches and carry my mountaineering boots. This keep trail dust from grinding into the seams of the more expensive boots.
