Even had it been the case that electrons got taken up by bare feet (a 
highly improbable scenario), they would have migrated to the surface of 
the skin [*], which consists of dead tissue. Apart from repelling the 
odd blood-sucking insect that had happened to have acquired a negative 
charge, it's hard to see what benefit could have accrued.

its surface because of electric repulsion.
