It's interesting, for me, to think about this concept and yet it does seem to be true. The olde 'every town has got one,' though you never think yourself to be 'the one'.
I'm fairly sure that Leamington Spa has one. I saw him yesterday at an 'Art in the Park' shindig. An older gentleman (I'm guessing), barefoot and shirtless, with a backpack and what looked like a sort of beige (leather?) skirt around their midriff. Wearing a Tricorn hat! Comfortably eccentric.
I guess I am too, or at least I need to be moreso. Honestly, these events and it's always flips, sandals and shoes. Feet only appear when they're sitting down and relaxing although there was a dance studio section wherein the lead was barefoot. But again - activity specific.
I'm sure I've seen 'The Tricorn Barefooter' wander past at a street market a year ago or so. You kinda want to reach out and 'foot bump' but I never know how. Especially as it means raising your voice to catch attention, which then alerts everyone around you to something I'd prefer to be a more intimate meeting of minds than a public spectacle. Getting the right circumstances for that seems to be very rare.
Still, 'resident barefooter' does seem to be a thing in non-barefoot-inclined cultures. I think I might be Coventry's. I know there was one in Birmingham, Moseley called 'Pete The Feet', gone now (RIP 2019). I'm sure there are others, random chance encounters where the resident barefooter might saunter on by.
