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)
Man I’m in my 30s and still do bunny ears to tie my shoes. Never really learned the “correct” way. My shoes do come untied a lot so maybe it’s time.
