Zone3 Elastic Laces

Elastic shoelaces for quick transitions by Zone3. durable elastic laces with a spring-loaded lock are perfect for quick transitions. You simply replace your cords with these elastic cords, use the double cord stopper to adjust the tension and tie off the ends, so they don't slip through the cord stopper. The ends of the cords are also wrapped to prevent abrasion and have a built-in reflective weave for night training. The elastic cords are strong enough to be adjusted to the desired tension. They are robust enough to withstand at least one season of constant use (including training) and abuse in the sun (UV) and moisture (salty sweat). The cord lock uses a stainless steel spring, so it won't rust or freeze.
