After a very long search for very lightweight (and short) approach skis that can be used with climbing shoes I finally found STC SnowVentureSTCSnowVenture. They appear to be the same as discontinued Rossignol FreeTrek. I did receive my pair but am yet to try them out. I had my eye on Hagan Nanook earlier, but didn't order them back then and now they are discontinued.
My reasoning for getting them is that some form of flotation aid is unavoidable in order to get to the climb if there's loads of snow. Usually full-on touring skis would be ideal up until you reach the climb, but they have few serious cons:
- if you can't leave them behind below the climb, their bulk can be awkward when climbing
- you need to have skiing boot to use them. Granted, you could climb with them, but they are heavy and way too stiff unless climbing is technically straight forward
Downhill, real skis paired with proper skiing boots would kick ass, particularly if you can maneuver them. Short skis paired with light weight and far less sturdy climbing boots are way worse for downhill, but not being much of a skier myself, I figure short skis and climbing boots are better solution for my needs. It remains to be seen whether this reasoning is valid.
