For most of the last decade I've worn sneakers shoes with no visible branding unless you're very close or can look at the sole, even though they're by major shoe companies everyone knows. My current daily walking around shoes have a logo but it's smaller than my pinkie fingernail and I have to squint to notice it. You don't have to be a billboard if you don't want to, and you can still enjoy the comfort of good design/manufacture at very reasonable cost.
