Zone3 Elastic Shoe Laces - 2021
Top of the range, heavy-duty elastic cord laces with a spring-loaded lock are perfect for speedy transitions. You simply replace your laces with these elastic cords, use the dual cord-stopper to adjust the tension, and tie off the ends, so they don't slip through the cord-stopper.
The ends of the laces are also shrink-wrapped to prevent fraying and have a built in reflective weave for night training.
The elastic laces are strong enough to be adjusted to any desired tension. They are robust enough to withstand at least a 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 up.
