High Sierra Topix

Hi, so I want to buy a new pair of hiking boots for heavy backpack travels.
As an Ex-military soldier I spent so much time and marches with Belleville 300 combat boots.
These boots were very comfortable to wear, waterproof and has a great thick Vibram outsole.
Obviously civilian quality boots dedicated for hiking would be a better option for travelers.
I searched for the best brands such as Asolo, Salomon, Merrell, Lowa etc.. And they come with a price tag.
The military boots can cost nearly half the price, and I used to wear them alot, so I have no problem to buy them again.
After a quick look on the internet I noticed there is a big selection of military boots and brands like Danner, Bates.. Rat boots, tactical boots,lightweight boots, hot weather/temperate wheather.. etc..
I'm looking for a quality leather boots for heavy backpacking with Vibram outsoles, waterproof, durable for leg protection, help to avoid slip, and reliable boot that will last long enough.
If you fimiliar with military combat boots, I need your advices.

Thanks in advance

For the price, and since the Belleville's already are a good fit for your feet, which is the most important thing, I would stick with them.

You're used to rucking with much higher than average backpacker's loads, and if the Bellevilles worked, consider staying with them, but the weight and steel toes of the 300s aren't going to be necessary. That said, if you're ready for a change and want to stay in an AR 670-1 compliant boot, we've been really pleased with the Garmont T8 Bifida, or if you want something lighter, the Garmont T8 NFS. Both are running about $140-150.

Also, a lot more people are switching from boots to trail running shoes, which can often run over $100 for a pair of good ones. In a civilian boot, I've always been a big fan of Zamberlan, but they're going to run you north of $300.
