Since we're talking about boots, I have a question too: Everybody seems to say plastics are the thing if I want to do stuff like rainier, and something like the trangos is better for stuff in the cascades. The trango bit I understand, but plastics sound like they'd be...well, plastic, inflexible, clunky, etc. If I'm gonna be walking up a glacier, don't I want my boots to flex a bit? Any leather boots that are good for stuff like rainier, hood, etc? Something like La Sportiva's Nuptse or something? I apologize if the answer is actually obvious, I am a newbie about mountaineering.
