I think the way to go right now is to create or post in broader, more top-level kind of communities. Lemmy doesn’t really have a lot of traffic, and what would probably be a small or medium community over on Reddit is a niche community over here.
To avoid that, find or make something like /c/shoes then post your Vans content there. You may find a larger audience more quickly, and can break out in to smaller subcommunities when there’s enough content submitters to justify it
