Yep always a hot topic this one.
No one seems to mention Meindl Boots. I've a pair of Island Pro's and they are the best boots by far I have owned /worn. Several mates have them too and we all think they are the poo. Mainly they have a strong following within the hunting crowd, You find them in most good gun shops in OZ. Go to NZ and they are also in the camping shops. Not cheap though but with these I find you get what you pay for. Never a blister straight from the box into a steep weekend hunting trip (Heavy load) on the fringe of Barrington Tops (Not tracks, just steep hills and a lot of scrub) As far as boots go I couldn't recommend them enough but they are a bit heavy @ 1150g each shoe. Other than if you get water over the top they are like wearing gum boots as far as water goes. Like any solid boo though, get them wet and they dry slow. Met a few Kiwi trampers wearing them and they had drilled holes in the sole to let water out quickly.
Mamut also seems to make decent boots (My walking mate has a leather pair he likes that are a few years old and still alive)
Now I'm a light weight runner man. As it's been said and many are against them for the reason of no ankle protection, too much foot flex, soft soles etc. That's a personal debate and I do believe you can re-condition your feet/ankles to be strong and use runners. That's if you don't have rubber ankles from previous injuries and I understand many are in that boat and boots will be better. Just don't think you'll walk straight out the back door with a 25kg back, offtrack for 6 days and you will be fine and feel better as you have flash light runners. Most likely you will be in pain for days and never wear them again. It's a process of time and if your packs over 15kg loaded I would probably not recommend runners as I believe the additional support of a boot is required with heavier loads. I must say I really appreciate the extra feedback from a track etc through the shoes being soft and flexible. It's also that feedback that causes a lot of pain if you've never done a few days with a pack in runners. Again, you just can't jump into them and tear off like boots. I feel the effort is worth it. I walked a few days a week after work on a rough track with a pack on for a few months getting used to the runners, after getting my legs/feet used to the runners I'll not wear boots again I fear. I must admit though that when I first purchased my inov-8's I lashed out 100km's in a few days on the GNW straight away. Man my legs were killing me and I thought my feet were about to fall off. I thought all this light weight shoe stuff was all crap. But it's not, you just have to ease into it.
As for offtrack. I do plenty and have never, never regreted being in runners since swapping. But again I'm fair used to them now and I feel that is the biggest factor. I think a light weight pack makes the biggest difference. In an alpine enviroment with fickle weather that's a lot harder to achieve, but still possible, just takes some effort.
I must say though that the lighter the choice of footwear, the less fatigued / sore I get after a long day.
Find that balance between the lightest shoe/boot you can wear that offers enough support/protection. Walker bliss right there

. Everyone will find that point in there own way, due to there own circumstances.
