Thanks for sharing this.
I'm "into" walking. But I don't walk barefoot outside. I live in a large metropolitan area & I don't think I'd want to walk barefoot around here.
I do walk barefoot in the house when it's warm enough to do so.
I used to have some Vibram running shoes that had toes in them. They felt very much like you were walking barefoot. They didn't hold up well on the concrete & asphalt though. And they were expensive. I was fortunate to get the pair I had deeply discounted at the end of the season a few years ago. I doubt I'd buy another pair.
