3mm Round Elastic No-Tie Shoelaces (Black Dash / Smart Lock - 100cm)

Best Suited For

The Coolnice 3mm Round Elastic No-Tie Shoelaces are engineered for low-profile casual sneakers, running shoes, athletic footwear, and everyday walking shoes. The 3mm narrow round diameter allows the cord to pass smoothly through standard metallic eyelets, fabric loops, and D-rings without adding bulk. Their elastic structure and smart lock mechanism are specifically suited for footwear requiring consistent, adjustable tension without the need for manual tying, making them practical for runners, children, seniors, and daily commuters.

Material Performance & Structure

• Durability & Stretch/Tension: Constructed from high-tensile core elastic, the laces stretch to accommodate foot entry and reliably recoil to secure the foot, maintaining consistent pressure without losing elasticity over repeated use.
• Wear Resistance: The tight outer woven sheath minimizes friction against abrasive eyelets, reducing surface pilling and fraying during daily flexion.
• Moisture Response: Synthetic textile fibers resist moisture absorption, sweat retention, and mildew accumulation, allowing the laces to dry quickly after exposure to rain or washing.

Aglet or Component Configuration

Each 100cm lace is factory-sealed at the ends to prevent unraveling during installation. The system utilizes a mechanical smart lock toggle that grips the dual cords securely at your preferred tension level. Available in multiple colorways, these laces integrate seamlessly into your footwear configuration while offering reliable hardware performance.

Care & Maintenance

To clean, wipe down the elastic cords and plastic lock components with a damp cloth and mild soap. If machine washing is necessary, place the shoes inside a mesh laundry bag and wash on a cold, gentle cycle. Always air-dry naturally; do not expose the elastic material or locking hardware to high direct heat, commercial dryers, or irons.
