Thanks for the info and the link!
I did some research and found the boot you are talking about. it was not well known for its durability among mountaineering/climbing/hiking folks. it was noted for soft leather, and premature delamination/unstitching. If memory serves they used a 2.2mm or 2.4mm leather that was dried, not oil or chrome tanned. Meaning it was a leather more like Asolo/La Sportiva/Merrill/etc use today. Beeswax, oils, animal fats, did nothing for this leather. It wasn't porous any longer, it only benefited from waxes, and silicones to help waterproof it. The leather could not be hydrated like oil/chrome tanned leathers.
Good boot for walking around/yard work from I've read, not so much for anything serious.
oil or chrome (Nicks, Whites, Wesco, Meindl, Alico, Limmer, etc) tanned leather is the way to go, IMO. Durable like all get out, easy to hydrate the living leather with beeswax, oils, and animal fats to help keep supple, and repel water and dirt.
Modern boots aren't designed for rebuild/resole, they are designed to wear out and get a new one. They are nice to put on and not have to break in though!
Thats my rant at least.
