Keep your work boots on tight with KG-Xtreme heavy duty boot laces. These 100% Kevlar and heavy duty nylon laces are braided together, wax coated, and then flame resistant fiber tipped to form the toughest lace around! These tough, durable laces are chemical resistant, fire resistant, and virtually unbreakable. They make the perfect gift for any welder, machinist, firefighter, construction worker, or anyone else in your life that wants laces as tough as the boots they trust each day! Most 6” work boots use 54” laces and most 8” work boots use 72” inch laces, but for best results measure your existing laces before ordering.
