I keep hearing about the benefits of walking barefoot.
One benefit I hear is that walking barefoot "[allows] us to synchronize with the earth’s natural electric charge" (source). This sounds like BS to me, but I wouldn't know any better.
The other benefit has to do with improving posture. I think the argument is that a lot of people's shoes are not tailored to their feet, and this can lead to posture problems down the line.
Is there scientific evidence backing this claim?
