I'm planing on taking the Yamnuska Snow and Ice Long Weekend class in September. The final day includes a summit attempt on Mt. Athabasca (3491m). I'm looking to buy my first pair of mountaineering boots for the trip. I'm hoping for something fairly versatile, but I guess that goes without saying.
I have a tendency towards cold feet, so I'm currently looking at double boots. The La Sportiva Baruntse has come up on my list so far, but I'm worried it might be too warm. Unfortunately, I'm not seeing any lower-end options for double-boots. I have hopes of doing some climbing on larger mountains than Athabasca in the future and I camp in the winter time in Maine, where temperatures can be down to -20 degrees, but tend to hang out more around 0. There's a lot of standing around flapping gums on camping trips, so warm boots are a must in this situation as well.
Anyway, I'm pretty new to gear this technical, so any information that you could provide would be much appreciated.
