Similar to ours just not crammed into shoes with tiny toe boxes. If you look at a baby’s foot their toes are spread super wide which is how human feet naturally are, but most shoes cream your toes causing you to develop narrowed feet over time.
I started wearing barefoot shoes two years ago and my back no longer hurts when I walk, and I can walk 10+ miles now without my feet killing me. It took a few months to get used to but once my feet adjusted they got much stronger. Now normal shoes are painful to wear and difficult to balance in because I’ve gotten used to being planted firmly to the ground.
This is incredibly common in SF. Many people live in co-ops and it’s created an entire subculture where they coordinate large parties and events both within the co-op and with other co-ops. It’s gone beyond necessity and become preferred by some because they enjoy living with lots of others. Not my thing, but many friends live in co-ops and love it.
