Shoelaces were first used by ancient humans as early as around 4000 to 5500 BC, with archaeological evidence including the Areni-1 shoe from Armenia, which had leather cord lacing. Early humans used animal sinews, leather, and plant fibers as laces to fasten footwear. The modern shoelace, with its small protective metal or plastic tips called aglets, was invented and patented by British inventor Harvey Kennedy in 1790, which made shoelaces easier to use and more durable.
