The boots are indeed the real challenge. No manufacturer really focuses on the kind of gear I really want – and why should they, as the market is infinitesimal?. What I want is a really light, totally waterproof. double boot that is stiff enough to handle a steep descent from the high pass and yet flexible enough to be good for the long gentle ascent up the valley that leads to the pass. Currently I have the lightest of the plastic 3-pin boots (Garmont Excursion, a bit lighter and more flexible than the T-3’s that tortured Roger, and with thermo molded liners that make them really fit), but I wish for something in between them and the beefiest of the NNN-BC boots – and with a removable liner for week-long snow camping. But such a beast does not exist. I could go to the lighter AT boots, and many folks do, but I can’t bring myself to pay the full retail ($800 and up, and THEN I have to get new bindings to go with them) and have been unable to find any used in my size. Currently I am working on modifying my Garmonts – taking off the cuff, moving a buckle, and adding an integral gaiter. I’m getting the weight down, but more importantly I’ll get better range of motion in the ankle. Will I lose too much downhill control? That remains to be seen, but I have seen online reports of similar mods that are promising.
All the NNN-BC boots I have had my hands on do not have a stiff enough sole to provide the control I need to get down off a 12,000 foot pass in the SIerra – though they’d be lovely on the cruise up the valley, I’m sure. And I worry about how to keep them dry for a week or 10 days in wet spring snow – I never had any luck with that back in the leather days, My well-sealed boots would be dry for two days max and then wet the rest of the trip, no way I could dry them out. Plastic boots with closed cell foam thermo-liners really spoil you there. Warm and dry no matter how wet the snow or how long the trip.
Edit to add: I agree with Ross that I’d rather have a beefy boot on a skinnier ski than vice versa, and that is particularly true when it comes to wider skis. Trying to get a wider ski up on edge with a too-flexible boot is a losing proposition. Of course, some skilled practitioners can ski anything, anywhere, anytime, on any kind of gear. But I am a very long way from being in that category, and need all the help I can get.
