I've been doing fairly serious hiking in an old pair of Vans for a long time (no kidding). I just got these before a good long trip of serious hiking in Turkey, much of it on steep, slippy, sandy rock, and I cannot tell you how comfortable I was. They just feel rock solid - and fairly lightweight considering.

I had done a lot of research online about which pair to buy. I had tried on the "Col Mid" in a store in size 12; my gamble that this in a 12 would fit exactly the same paid off. The company rates these as "backpacking grade", and I think they are about as light as the ones in that category come. I did not feel fatigue from the weight, nor did I wish for something with more ventilation, despite the ~30C weather.

Quite happy with these.
