Steel Blue Nylon Laces are heavy-duty replacement laces made to fit a wide range of Steel Blue work boots. They’re crafted from a super-tough nylon (polyester/CORDURA) material that exceeds industry standards for tensile strength and abrasion resistance, so they last longer in rough work conditions. Available in multiple colours and lengths with options up to 160cm long to match different boots and lacing needs for most lace-up safety boots.
