You are spot on about this shoe. I live in the sierra nevada mountains. I've worn these shoes almost every day for over a year, when much of the time I would have been in hiking boots. The only times I didn't wear these was when I was in ski boots or sorrels (due to deep powder). They have excellent traction on ice and hard pack snow as well as rock. These shoes were perfect for an ascent of Mt. Ritter from my house, which involved hiking in with a three day pack, rope, harness, sleeping bag, etc. They worked well with strap on alpine crampons for the snow field and climbed great on the 3rd class rock. Heavy? I don't think so when compared with the alternative- a light mountaineering/hiking boot. Did I mention they have great support for hiking with a load? Better than many high top boots, due to the heel wrapping rubber .
