To expand on this, unless you are essentially just an atelier, or a bespoke maker with your own manufacturing facilities (like Rubinacci) or have very limited offerings (for example, Wings+Horns really just makes 2 sneakers, in different colorways) you'll find that nearly all companies use a variety of different factories, and that these factories can change from for year to year, season to season.
Sneaker factories are booooorrrrrrring. This from a guy who wears sneakers most of the time. It's much more interesting to go to a "proper" shoe manufacturer, especially some old school company like the English have in Northhampton, where you go from some pretty mechanized outfits to some people who still do things primarily by hand.
