@Heffboom_Konijn i don't know much about alt-right symbolism - but i do know that white shoelaces are a very easy canvas to dye if you wanted to do that, and have time to do so (perhaps overnight)
you could dye them with food coloring http://silverliningcrafts.blogspot.com/2012/04/cool-technique-for-dying-shoelaces.html , tea/coffee https://www.instructables.com/id/Natural-Dying-With-Tea-Coffee/ , or koolaid https://www.instructables.com/id/Kool-Aid-Dyeing-for-Lace/
or for a more authentic hardware store look, you could just hasten the usual process of any white footwear on the worksite and dirty them up a bit lol
@wigglytuffitout thank you ^^ that helps
