"Skiing the buttress in the sense that I will have skis on instead of snowshoes up to 11K. Not planning a ski descent or anything, just prefer to be in skis than in snowshoes for the lower part of the climb."
That's exactly my point. Your only using the skiis to 11 000 and it's not technical ski terrain below that. Who cares if they're a bit sloppy. In your initial post you asked for solutions to the "problem", there are no solutions to the "problem" (other than common sense such as tightning laces and getting used to them), that's how Mountaineering boots ski.
