anything that's goretex, its polishable (sp?) really waterproof, breathes well, good during winter with wool socks on, and nice during the summer with thin socks on. As per brand, most boots are reliable, as long as you polish them and take care of them. To me boots are important, they take care of your feet, so I take care of them lol. As per whats most comfortable? well we all have different size/shapes of feet, so my recommendation is go somewhere that has lots of black boots, and try on like 15 different pairs, ignore the pricetag, see whats most comfy for you. I have really wide feet, so the boots I would personally recommend might suck for you.
oh another thing, don't use that kiwi quick polish stick :censored::censored::censored::censored:, over time it will eat through the boot super fast, when I was on basic training way back in the day, one of the recruits got in MAJOR doodoo because the leather on his toe started peeling from using the kiwi stick too much.
