Of the brands mentioned, I think you can be choosey and find something that will meet the need. Single-piece leather construction boots... or as close as you can get to that... will be darn close to BIFL if not truly BIFL when maintained correctly. Choose good boot maintenance products with nontoxic qualities, keep your boots cleaned and well oiled to prevent water intrusion, and you should have a great pair for a very long time.

I personally sprung for Asolo boots a while back, and those look nearly as good as they did when purchased nearly 15 years ago. I use these to traverse hard ice, snow, mud, and everything in between. Manage the woodlot on my property. Scuff them against rocks on occasion when hiking too. They just keep going! They are thick leather, and with a thick pair of winter socks I've been comfortable down to -20F.

But you don't have to buy Asolo to get that, other companies also produce single-piece leather boots with minimal stitching. Remember, stitching = increased weakness in the material. Good luck!
