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)
Yep, found that out a few years ago. Now I start tying my shoes with right-over-left, so I’m doing a square knot bow instead of a granny.
Right-over-left for the starting knot, then the classic rabbit-round-the-tree for the finishing bow (which is left-over-right for me), for the win!
