Doc Martens are unrepairable garbage now. If you're looking for the modern equivalent of oldskool Docs,
NPS/Solovair is carrying on that tradition, as they were the original company and manufacturer that was responsible for manufacturing Doc Martens up until the 1990's, and are the
actual people responsible for the legacy of durability that the current owners of Docs is cashing out on. Note: not all of the Solovair catalogue can be resoled, but most of it can, IIRC. It's worth noting their catalogue isn't ALL boots. There are loafers, monk shoes, and mary janes as well. I want to say it's only their sneakers you can't resole, but don't quote me on that.
This said, not a lot of cobblers in the US are willing/capable of resoling Solovairs (or older Docs), due to the PVC outsole being melted on to the Goodyear welt... unless you let them completely redo the welt and go with more traditional soles after that, but that switchover can cost almost as much as the initial shoes, and there aren't a lot of cobblers left willing to take on such a large job anymore.
This said, if you want to know who makes the best repairable shoes today in the styles you're after, maybe just ask your local cobbler for recommendations when you go back to pick the other shoes up. After all, you already have a cobbler you trust, why not ask the very people who would be doing said repairs what shoes they would recommend?
