Caterpy - Run No-Tie Shoelaces - Standard (30in / 75cm) - Sand Dune Originally invented and patented in Japan, Caterpy laces are the first true no-tie shoelaces that require zero hardware--no clips, clasps and stoppers. Dial in Tension Easily With Caterpy's Bump Technology You can adjust the tension of Caterpy's no-tie shoelaces thanks to their 'bump technology'--these bumps keep things as tight as you want without loosening over the course of a run, hike or wherever your feet take you. What Makes Caterpy Great? You can tune every part of your shoe's upper to your foot's unique shape. Lacing up with most stock and traditional laces give you a fit that's either too tight or a little loose. Caterpy gives you the right amount of stretch and tension to stay comfortable but secure when running, hiking and getting after your day. Elastic laces have been around for years. But not all no-tie elastic laces are the same. Caterpy solves the issue of (potentially) breaking parts (e.g., fasteners, clasps, etc) while giving you a way to right-fit your shoes easily every time you slip them on.
