I'm 11.5 4E with duck feet (very wide forefoot), no arches and cankles. this is, naturally, quite difficult to find good fitting footwear. normally wear New Balance shoes in 11.5 4E or Magnum boots in 11.5 wide.

my pair is the high top in tan
ordered 11.5, feels true to size in length (as previously pointed out, the toes fit differently than other shoes)
forefoot is snug for me, but comfortable
plenty of room in heel and ankle
insole is fine, but next to no (proper) arch support.

very breathable, has venting (probably not waterproof), look to be quite cool. forgive me if I don't feel like taking a hike at night in Calgary this time of year to find out for sure.

if you're a fully grown adult with normal feet and you know your properly measured foot size, they'll be fine.

addendum:
the tongue on these boots is practically non-existent over the top of the foot. if you're prone to lace bite on top of your foot this, and the thin laces it comes with, are your wost nightmare. the shins are much better. however, it does make the whole shebang quite light.

the ankle is incredibly flexible. it feels like wearing a regular shoe with a sock attached to the top. not entirely convinced it'll do much if your roll it, but I'm not going to go step off a curb funny to find out.

put in a different insole and changed the lacing pattern, now very comfortable for me.
