When I buy a pair of shoes with the laces on them, they are often laced so that when the lace goes through the last eyes (the pair nearest my ankle) it comes out under the flap of the shoe and goes over the tongue. When i lace shoes myself, I lace them so the lace comes out over the top of the flap of the shoes and then goes over the tongue.
I've never understood if there is any significance to lacing shoes one way or the other. Is one way better for my foot or the shoe? Is one way some kind of fashion statement? Could it be misinterpreted as a social signal? "I am a freemason" or something like that?
