Assuming anyone still reads this particular forum at this time of year!
I have bought a pair of Intuition Sports custom boot liners for my Koflachs. They are apparently a lot warmer than the standard Koflach liners.
I will go to a ski shop to get them molded correctly but was curious as to people's experience with them. They seem so flimsy compared to the 'less warm' standard liners. They are much lighter, though - a big plus.
I will use them for mountaineering, although perhaps they will be useful for iceclimbing too.
