No socks?

I can’t be the only one that wears shoes with no socks sometimes cause it just looks better. Anyways, I wear vans with no socks and wondering if anyone knows of any good tricks of preventing really bad feet smell when I take my shoes off afterwords. My feet always smell horrible and nasty along with my shoes. This doesn’t happen when I wear socks. Anyways, any tips would be helpful. I’ve tried that foot/ shoe powder but that doesn’t help much.
