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.
