What do you think about the Lowa Mountain Expert GTX Mountaineering Boots? I used them on Mt. Rainier and they kept my feet plenty warm, but I was wondering if you thought they might be suitable for Pico de Orizaba in Mexico. It is about 4,000 feet higher than Rainier. I don't relish wearing double plastic mountaineering boots anywhere, and hey, the red color of the Lowa is, well, cool . . . Stan El Dorado Hills, CA

Climbing El Capitan without rope, gear, or safety net.

I purchased a pair of Scarpa Summit GTX mountaineer boots, kind of on a whim (I'm a gear nut).
