I've skied a fair bit in mountain boots. Its a poor craftsman that blames his tools...ha ha.
Here in the Wasatch, there was a time when folks ski toured on tele gear but made mostly parallel turns. Tele-llel or paramark or something. Anyhow, when I figured it out (I remember that day with clarity), I spent a bunch of time skiing with my heels not attached and making standard parallel turns. Made the transition to skiing with a mountaineering boot not that difficult, I'm guessing. Especially after so much time ski touring in floppy leather boots.
I'd much rather climb in a climbing boot and do a little skiing on the approach and egress than the other way around. For short routes or days, the ski boots climb ice fairly well.
Absolutely! I was going to say that if you can ski 45 degrees in leather 3-pins, you should have no problem skiing in climbing boots, just not my cup o’ tea:)
I spent the day putting my Hojis through the paces at the Ouray Ice Park today. I tried aluminum and steel 'pons. Popped an aluminum crampon, too flexy for steep ice. Sabertooth semi-autos did fine. All TR, climbing steep (WI5). I was very pleased with how the boots did; they were as comfortable or more than my mountain boots. Just heavier.
Also FWIW just sold my silvretta setup. Skiing in mountain boots, even on trails, is horrible. (I learned to ski in koflachs with silvretta bindings on vintage Trucker skis. Upgrades to skis and boots did not help.) I think the modern lightweight warm ski boots are a better option.
Finally, if you are uncomfortable climbing in ski boots, pair of Dynafit Blacklight pros with pin skins and superlight 150s no brake but leashes, PDG boots, and a pair of mountain boots in your backpack is still lighter than almost any touring ski with silvrettas and full length skins skiing in mountain boots.
