Yeah, while I think there's something in the whole VFF phenomenon, and I'm not a big believer in the idea that things can be over-thought, this is too much.
I understood it. But then, I edit writing for a living. I'm also prone to over-clausing myself.

1) He think's there's something to the VFF phenom.
2) He's believes that over-thinking isn't usually a problem.
3) Despite those two things, the over-thinking here is too much.
It makes sense if you sub out the commas for periods, and think of this as something that someone said, instead of wrote.
Anyhoo... Barefoot, I really do think that you're spending more time worrying about what MIGHT happen, instead of what is LIKELY to happen, and all of that worrying is wasting time trying out the shoes and seeing what DOES happen.
I've been wearing the shoes for several months, and I can count on one hand the number of strangers who have said
anything about the shoes, and all but one have been positive (and the one didn't say anything, just looked alarmed). I'm not an exhibitionist, so I was dreading this a bit myself, but you know what? Screw 'em. They are random people who you'll never see again.
Family, friends, and bosses are harder to deal with, sometimes (my friends all found the shoes intriguing and cool - and now they're used to them and ignore them) and I don't wear them to work.
Overall, you're giving the impression of someone who DOESN'T want to buy or wear VFFs.
So don't.
Or do.
But, really, truly, honestly... you are getting immensely worked up with might-be scenarios that could be dismissed
in an instant by getting a pair and
trying them out. At this point, you've read all the boards, you've read all our responses, and you are STILL unsure.
So at this point, fish or cut bait. Try the shoes or don't. They will either work or they won't.
It's
just that simple. Don't make it more complicated than you need to.
Really. It makes ME anxious reading what you're writing here, and I'm worried for you.

Try on the shoes. Or don't. But, please, stop worrying so much about things that may or may never happen.
(Ants? Syringes? I mean, good lord. That's like 1% of possible problems, and yet that's keeping you from just
trying a pair? Most people worry about things like dog poo and glass, which are at least common dangers - and dangers that one figures out aren't much of a big deal after all.)
