My recommendation would be to just try it out, to feel for yourself.
Just because something feels good, doesn't mean it is good.
Not always, yes. But in this case I can test it by general wellbeing and shape of feet. The more I walk barefeet on grass and rock, the stronger my feet are. And more sensitiv. With shoes, I don't really feel my feet, with barefeet I can now feel the grass on different parts on my skin. Feels good. Improves my mood -> is good for me.
While that feels good for you, this does not constitute the evidence that "going barefoot is good for you." A sibling posted some studies that would be more interesting (I'll admit I've not read them).
What "good for you" would look like to me would be longer life expectancy, better health outcomes at different stages of life, etc. "Strong feet," for example, doesn't meet that standard for me. I'd want to see a link that work to actively strengthen one's feet creates those better life outcomes.
Do you need a study for every little thing?
You body does provide you with a quite elaborate feedback system. And you can also objectivly meassure. (E.g. how long you walk without pain)
And studies can be very misleading. For example it matters a lot, if and how often you walked barefeet as a child. If you didn't, your bones will be not so strong developed and then barefeet walking/running can be even dangerous. Trusting a general study that maybe did not take this into account (or did not mentioned it prominently) here vs trusting the feedback from your nerves in your feet would be not wise.

I didn't say that. What I said:

"It feels good" isn't an objective outcome that necessarily means something is "good for you."
> And you can also objectivly meassure. (E.g. how long you walk without pain)
This is a better outcome but I'd say it's not objective because I walk without pain while wearing shoes.
