boot quality is not necessarily dependent on location of manufacture. Also, considering you've got seven years on those boots and they look better than they did when new, I'd like to know the extent to which you actually put those boots to work in snow/mud/rocks/rain because if I can get that much use out of a pair of work boots then damn I need some of those.
Yeah I know what you mean, I thought the same. I'm only claiming it's the best place because I haven't found so good a pair of boots in most other countries I've travelled to (then again, the leatherworker was in the business for generations from what he told me, so it could just be that particular shop!)
She always wears them through rain, mud and snow. Rocks? The soles are very resilient, but I'm not sure the leather around it would stand rocks.
After a tough day she usually cleans them in soapy water, rinses them, buffs them, some spit & polish and another couple buffs, and they are done. The best wax to use is Kiwi's wax, I found.
The boots were handmade.
