I've just started wearing this sort of boot in the last couple months, but hopefully this info helps. Steep/backcountry capable boots are based more on the user's feet than the boot itself. It takes some time and effort to get worked up to using them.
Ankle Support-This is a misconception IMO, there's no such thing as true ankle support in anything less than a motocross/ski boot. Barefoot boots results in waaay less tendency to roll an ankle because they're not platform shoes that force the foot to roll with the stiff bed of the boot.
Traction (I have heard that Vivos get slippery)-Steep, frozen terrain is the Vivo achille's heel IMO. Strap on spikes help. Aside from that, the grip is good.
Quiet-Vivos are very quiet. Anything barefoot will be quieter than stiff boots.
Light-Anything barefoot/minimalist is going to be lighter than anything that isn't.
Waterproof-There's no such thing, unless it's rubber/plastic. Gore-tex is nothing even remotely like waterproof in a boot. Very heavily waxed leather is as close as it gets. Something without a liner will dry much faster.
Ideally made in USA-Nick's is probably the only option. They're wildly expensive and less minimal than most barefoot type boots.
Reading the threads on the various types of barefoot/minimal boots will help. Lots of good info in each of them. To summarize the way I understand the various options:
- Vivo-Full barefoot. Excellent durability overall, top notch leather and soles. Need to work up to hunting in them. Spikes needed for steep, frozen terrain.
- Altra/Inov8/Topo-Kind of a happy medium. Not remotely waterproof, questionable durability. Squishy foam probably doesn't do well in steep, frozen terrain either. Light and comfortable.
- Jim Green/Nicks-Traditional leather boot with a barefoot sole. Factory JG sole is not great.
- BAR Bergkomfort Wanderstiefel 2.0-Maybe the ideal happy medium. Expensive and not great CS. Only available from the manufacturer in Germany.
