Old Kook's Dura-Force Work Boot Laces are the toughest, strongest and most durable laces for work boots, construction boots and all industrial applications. Dura-Force Laces are made from super high-tech fibers which are braided to create shoe laces that are -- literally -- stronger than steel cable of the same diameter (Over 1600 pounds tensile strength).

So, not only are they the strongest shoelaces in the world, they are also the toughest! They're coated with urethane for maximum abrasion resistance. Old Kook's Dura-Force Work Boot Laces are far superior to standard work boot laces and better than any replacement laces available. They are the same as Snakes! Laces, but in longer lengths, suitable for all heavy duty jobs.
