@deathcon4 Personally I think that doesn't exist an specific school of shoemaker, there are some designers and patternmakers schools but this in only one little part of the process of making footwear. I have been linked to the shoe world since my childhood and have always worked on it. Manufacturing shoes has envloved in several crafts jobs so training in all requires a lot of time and experience. Generally you can learn next to a master shoemaker and as a rule each shoemaker specializes in a specific sector.
There are a lots of books and publications about this, but you would need last or do them yourself to start practicing. My recommendation is to look for work in a shoe factory.
Good luck and hope you get your illusion.
