In reply to Pietrach:
This is not a direct response to the OP's question, but I had a revelation last summer. I did a long hike in sandals and took along my regular summer hiking boots. I managed to walk through small patches of late-season snow by being careful. I did not put on my hiking boots.
I thought I'd try it again, and throughout the rest of the summer I walked in the same sandals. I did take along a pair of trail runners, but hardly ever used them, mostly on the descent. I was able to climb class 3 and 4 scrambles in the sandals. It made me think more carefully about where I would place my feet and I think it contributed to my feet being not so "beat up" after the hikes.
Last year in December I went for a trek to Annapurna Base Camp. I walked up and down in sturdy hiking boots, now, after last summer I think sandals could have been a better footwear.
I know I'm comparing apples to oranges for conditions, but it is worth considering going as light as possible. I was surprised at how many peaks, about ten, I was able to top out on wearing sandals.
