I suspect they mean on black 'bovver' boots, Lister.
I too heard of them as meaning adherant of white supremacy.
I went googling though, and shan't post a link because of the language, etc., but I liked the intro on bootdog dot com's lacing page
Those 'para' lacings on the OP's post would do my head in. I couldn't be bothered to do all that fussing around trying to get them comfortable. That looks like worse than corset lacing. No wonder he bought zip up boots
I admit that I still use the old method where there's one lace end does the whole lace up, while the other lies underneath and goes from one bottom lace hole up to the top opposite one.
Easy, secure, fuss free, quick to adjust, and simple to get off if necessary.
cheers,
Toddy
