Shoe lacing systems aren’t really new, but these shoelaces are unique. If you stretch the lace, the knots disappear, allowing you to thread the lace through the eyelets. The lace cannot slip or accidently come loose.
Take your shoes on and off without having to tie your laces.
Thanks to the large amount of knots you can easily adjust tension. More knots between eyelets lessen the tension; fewer knots between eyelets increase tension. Once adjusted, the selected tension will remain the same, so you won’t have to re-adjust them over and over again and you won’t trip over loose laces. They also eliminate foot compression when the feet swell while you exercise.
