Why YSK: The granny knot is the most common reason as to why show laces seem to be undone so easily. It’s caused when the Starting Knot & Finishing Bow don’t “balance” each other. Recognizing this can help you make your shoe knots much more secure.
Edit: (BTW, YSK the website as well. It’s a really good resource for tying and lacing shoes)
Oh my, I had this revelation about a year ago myself. Watched a video for tying my zero drop running shoes. Game changer.
The important and easiest piece, is at the beginning; simply reverse which lace goes over which at the beginning. Then do your loop as regular.
Reading this, I realize it’s hard to explain. But it’s worth it to master. Works on boots, too.
