No. I am saying the soles of the suit were made from some sort of white material, latex or something of the kind. I wouldn't have a clue if they were shoes or just soles.
But white shoes with white soles were around in 1967 - for example the below Nike running shoe. Remember, Bob Hieronimus was known as a football player, so it is likely he owned sports shoes. (Now, I am not saying he was wearing
that exact same shoe). But white shoes were certainly around in 1967.

People, 1967 wasn't the dark ages, really.
