Absolute comfort, durability, water proof, great support. I would personally recommend a Meindl boot. Have a look at their website (or if in BC, check AJ Brooks website).
Oh, btw... $$$ for Meindl but worth it! Got a pair, MINIMUM break in time, did a 13 KM march with 45 lbs ruck and did it in record time with only a couple hot spots on my feet when previously I had MAJOR blisters on my feet. I have since never regretted getting the boots and paying the price after that proving experience.
