I've read about barefoot hiking in the USA before.
As a kid I rarely wore anything on my feet when possible; that is when not at school, church, or wherever else my parents dragged me. I found shoes extremely uncomfortable (and still do) as I have very broad feet. Even in winter I would happily play in the snow with no shoes! Probably not for too long though...
I did have just one nasty incident: I was walking along a garden wall and fell off, into our rose patch. My foot got wedged and hooked by the thorns into a Y-split in the branches. That stung!
As an adult I haven't changed much. I never wear shoes around the house or garden, unless I'm using a spade or doing similar work where it's a safety issue.
I walked about 80 miles or so of the Pennine Way in just socks, when the blisters from my boots had got so bad that my socks were blood-soaked. It was much nicer, even the boggy bits.
Unfortunately, most of the places I get to have too much dog dropping around for me to go barefoot.
I've also popped the occasional large slug between my toes, when outdoors at night :aargh4:
