A secure shoelace knot with a simple, symmetrical method of tying: Cross two loops and pass them both through the “hole” in the middle. Great for serious sports or for securing shoelaces that are either too slippery or too stiff to stay tied with a regular shoelace knot.
Also known as the “Double Slip Knot” or the “Seemännische Schuhbandschleife” (Seaman's Shoelace Knot).
