This just strikes me as odd. In the 1940s there was a sudden fad of going barefoot among high-jumpers and and pole-vaulters.
But only half-barefoot.
Fútbol (soccer) is one of those games that just seem a natural for playing barefoot. It’s played on a large grassy field. You see kids all over the world playing that way. It’s probably safer played barefoot; with all that kicking going on, I sure would prefer that a misaimed kick come from a bare foot.
But you sure won’t see a World Cup game played barefoot.
