Human feet are designed to be super tough and i can see why people like them super soft....super soft feet would be a sign of great royality, never working class...
Shoes are harmful, socks almost as bad.....both destroy the health in ways that people ignore....
ONCE FREE
socks and bad shoes smother you...
Those that have an ocean to walk by daily have it made.....
and yes, worms/parasites can do damage from direct contact with the skin/feet, so proper internal health keeps them out...not wearing shoes and tons of cloths.
