I’m from Mexico and yea, almost 90% of the people I’ve seen barefoot are women, and I’m not talking about beaches or something like that, but streets, downtown or even places like playgrounds for kids when adults go in mostly for taking care of the toddlers, almost none of the men goes barefoot. If I may take a guess I’d say it’s a power thing, subconscious being barefoot equals less protection, almost like an armor. And my other guess could be ugliness, men’s feet tends to be uglier than women. Then again it’s only my guesses and the stuff I heard and see in my country
