Hi Gaucho, if you're buying boots for trekking around Annapurna, I recommend a lighter version of the boot, as most of the trekking is done on dry ground. Exception is just some pass that might be snowy. The boot should be comfortable, since you'll wear it practically all day, only afternoon or evening change to something lighter (sneakers,tevice,crocs,,,). These two models you're showing are already a bit higher end. I practice with two pairs of boots: one heavier, compact for winter ascents, others lighter for summer approaches.
Trekking boot should be stiff enough, but not too much. I like it to cover the whole ankle, so I can reduce injury risk. With lighter boots pay attention to the sole, that it's good quality, seams strong-double, that we can properly protect the leather, that it offers at least some protection from moisture. Don't forget extra, spare laces.
I did trekking below Everest and over some passes in lighter Alpinina hiking boots into which I added a thinner cork insole, which provided extra thermal protection, and I felt fewer stones on the path. If anything else interests you, just ask, if not, send message to ZS.
