I have never researched the shoelace industry, and I'm not a member of any shoelace forums, so I'll ask my MacRumors friends about this. When I buy new shoes for work (men's casual styles), they almost always come with round laces. The laces slip against each other easily, so they tend to come untied. It's a pain to use double knots, so I just retie them now and then. When I get tired of doing that, I buy some flat laces at the drugstore and replace them. Then I end up throwing out the round shoelaces because the clothing charities never ask for them, the laces don't make good spaghetti, and I don't need props for a movie named "Tiny Snakes on a Plane". Are these round laces a sinister plot by the flat lace vendors, who send a kickback to the shoe companies so they'll keep outfitting shoes with round laces? Or are round laces simply cheaper for them to use? Or are they considered better looking, even if they are less convenient, so I'm committing a fashion faux pas? What's the real story here?
