A flat waxed cotton lace from Italy in a longer length for taller boots, made by artisans with over 60 years of lace-making experience.
Being a fan of waxed flat laces and owning ones from many different vendors, these are the best ones I've ever used. Superior grip when laced up and ties down as tight as you need them. These will be the only ones I ever buy on future waxed laces.
