Yankz - Elastic Shoe Laces for Athletes - Reflective White Laces, White Lock
Yankz Laces, White Laces, White Clips were designed to meet the rigorous demands of serious athletes. The elastic cord gives slightly to allow for increased comfort while running. Unlike traditional laces, they have two points of adjustment (the ankle and the toe) so every type foot can be fitted in the correct way for its shape; this increases comfort and may reduce risk of injury. They never come untied, so athletes don't have to break from the action to adjust undone laces.
