If you REALLY want to get the absolute best boots you can own, there are two brands I can think of, one Canadian and one American.
The Canadian brand is Viberg. They hand-build boots in the same little shop out here that they have been in for about seventy years. The leather is 8 oz premium stuff, often cowhide, sometimes buffalo, which is tougher.
I have a pair of Vibergs that are about six months old. I wreck a normal pair of boots in a year, every year, without fail. I would guess my Vibergs are MAYBE 5% done in, tops. My dad, who was literally born in a mining camp on top of a mountain here in BC, has had the same pair since before I was born (I am thirty.)
Every other pair of boots I have owned, even the expensive stuff, I've needed to wear expensive insoles in to make them all-day tolerable. My Vibergs were built specifically for me, and I don't wear any insoles in them. They are more comfortable than any other boots I have owned, no matter what insoles I've had in them. They really are the best boots you can get.
The American brand which is similar (or was at one time but I haven't seen a pair made since about the 1980s) is White boots out of Spokane. The ones I saw were built very similarly to Vibergs, similar shape, similar construction. But again I don't know what they are like today, although I hear they still build good boots.
If you had a time machine you could buy a pair of Daytons from back when they were still in the logging boot business, or Paris boots before Punchy Paris packed it in and became a judge of all things. But Vibergs were just as good back then and are still available now.
No mass-market boot exists that competes with the small-market high end.
A pair of Vibergs built to your specs should cost around $450 Canadian, or $400 US.
Finally, here is an example of what the Viberg people are like to deal with. I went in their shop last August and told them I wanted a pair of boots made. The woman who was working their was about seventy, and wearing a pair of vibergs, of course. I remember her working there when I was a kid, twenty years ago. She measured up my feet in a bunch of spots, explained why normal boots would give me trouble (Huge feet, narrow heels) and wrote up a bill for a new pair of boots that would custom-fit me.
"Okay," I said, "so, how much for a deposit, then?"
"What deposit, for what?" she asked.
"For the boots," I said, "Do you want a deposit on custom work like that?"
"Well," she said, "you can put down some money if you want. But you're coming back for the boots, eh?"
"Sure," I said. "When will they be ready?"
"Six weeks," she said.
"Okay, then, I'll see you then," I said.
And I left. They didn't want a deposit on a $450 pair of boots that wouldn't fit anyone but me. They just built them and phoned me when they were done.
These guys are really something else. I encourage anyone with the money to deal with them.
