Coolnice 3mm Round Wave Elastic No-Tie Shoelaces (Smart Lock - 100cm) provide a practical, conversion-optimized footwear modification designed to eliminate traditional tying while maintaining consistent tension. Engineered for everyday convenience, these elastic laces transform standard lace-up shoes into slip-ons.
Best Suited For
These 3mm round elastic laces are structurally optimized for casual sneakers, running shoes, athletic footwear, and everyday walking shoes. The 3mm diameter and round wave profile fit standard eyelets smoothly, allowing the elastic core to glide through eyelets during tension adjustment without binding. They are widely utilized by runners, athletes, seniors, children, and individuals requiring quick-footwear entry.
Material Performance & Structure
- Durability & Stretch/Tension: Manufactured from high-tensile elastic rubber threads encased in a woven textile sheath, providing reliable recoil memory and consistent foot containment during movement.
- Wear Resistance: The tight outer weave resists friction against metal and plastic eyelets, preventing premature fraying and surface pilling under repetitive mechanical stress.
- Moisture Response: The synthetic fibers shed surface moisture rapidly, resisting sweat absorption and drying quickly after exposure to wet conditions or routine cleaning.
Aglet or Component Configuration
Aglet Options: Finished with durable tips to prevent fraying. Metal aglets are available across all 27 colors, while plastic aglets are available on select colors. Choose your preferred tip finish from the options menu above. Each set includes the proprietary Coolnice smart lock mechanism, which mechanically secures the adjusted length without slipping.
Care & Maintenance
To maintain structural integrity, hand wash the laces in lukewarm water using mild detergent. If machine washing, place the footwear inside a mesh laundry bag. Air-dry naturally away from direct high heat sources such as radiators or tumble dryers to preserve the elasticity of the core rubber fibers.
