Side Lace Lock – Shoelace Holder

Summary

A lightweight, ultra‑compact and efficient system designed to lock your shoelaces without tying a knot.
These side lace locks attach directly to the last eyelet of your shoe (one on each side) and guide the lace through a multi‑stage path that increases friction and keeps everything securely in place.

Perfect for running shoes, sneakers, work shoes, or anyone who wants a clean, knot‑free look.

🔧 How It Works

The lace follows a three‑step guided path:

• Central Hole
  The lace enters the main 4.1 mm hole, which keeps the lock aligned with the shoe’s eyelet.
• Upper Hole + Grip Surface
  The lace exits the central hole, re‑enters the upper hole, and passes over the textured grip area.
  This increases friction and prevents slipping.
  The lace passing over the lock also prevents the part from touching your ankle.
• Lower Slot Locking System
  The lace drops into the lower slot, where the narrow geometry locks it under tension.

The result is a stable, adjustable, knot‑free closure.
