The video I posted was wrong. I use your method but on the first "half knot" I wrap twice. It does not allow slippage when making your loops and it helps keep your heel locked in place. I've also found using waxed kevlar laces keeps things more secure while tying and after it's tied.
Thanks for making the video.
That would be a surgeons knot in style, and is the exact purpose. I find the longer bottom half not using that technique actually makes my loops more likely to work loose as it limits the tension for the top half knot.
The double turn on the top locks the loops as securely as a "double knot," but unties easier. Well, in my experience, more securely as I have had "double knoted" laces come undone hiking, I have never had the improved shoelace knot come undone (my name for it, I've actually not encountered it anywhere, but I'm sure someone else has done it).
I've also tried two turns on both bottom and top, it was no better than a standard shoelace knot.
With high topped boots, gutted 550 cord laces, wrapped around the top of the boot to take up the excess, and tied with a square knot works, but I've stopped doing it as the improved shoelace knot holds just as well.
If I come across some waked Kevlar, I'll have to give that a try.
Ok, I'll stop showing what a nerd I am. OP, sorry for thread jacking.
