Here's your best anecdote of a single person testing the same military boot.
The one thing I don't agree with him is how he downsizes to a point where his toes barely touch the length of the boots, but bellevilles worst design tends to be how snug their laces hold.
Certain belleville models (mini mil, xero) and garmont bifida t8s tend to be the best.
T8 nfs weighs less but won't last as long for eva foam.
Bifida t8 tend to last longer as polyurethane but weigh more.
https://www.frankrevelo.com/hiking/gear_footwear_belleville.htmI'd say the one caveat with military boots, which is the same as trainers is that they are designed to function for a set time (ie a mission, training, few months) in general. Eva shoes are stated for the foam cushion to last 500 miles before it breaks down.
Boots now use the same eva foam and sometimes polyurethane (more durable) but the leather tends to be some of the lowest quality (suede) you can find.
A lot of people buy new boots for a new combat school, deployment, etc for that reason. So don't be surprised if you buy some and don't use it for a year (hydrolysis of foam, or leather dries out and cracks) and your boots are doa upon the time you break them out of the closet.
I'd still aim for boots around or under 3 lbs as getting some type of station boot across a profession like 5 lb logger boots or 4 lb Corcoran jump boots or most other welted boots will be really hard on your joints down the road.
