I don't exactly know what all Mount Shasta entails, but I'll give my shot at a reply. These may not be quite sturdy enough for serious mountaineering. There is some flex above the ankle and it seems that the leather is breaking in after wearing for a few months (maybe about 15 miles of hiking/week). The softening makes them comfy, which is nice, but they are not of the traditional stiff-mountainineering boot variety that you may be looking for. Hope that helps!

I'm not certain if crampon will work on this shoes. I would probably look ASLO and other higher approach shoes that are design for it. This shoes seems nice by itself and vibrate sole are sticky. Leather is soft with suede finish.
