It pains me to see a youtube celebrity like SJD whose main claim to fame is doing shoe reviews tie his shoes with an unsightly granny knot and have to double knot them to keep them from coming untied. And in Sage's recent Torrent 2 review he said he sometimes even triple knots his laces! This is madness. Somebody please stop them and teach them how to tie their shoes in a square knot.
In the years since I learned about tying shoes with a square knot instead of a granny knot, I've never double knotted my shoes and only had them come untied one single time. If you're really paranoid you can still double knot for an important race, but with a square knot there's no need to double knot the other 99% of the time when you're doing training runs. Additionally, square knots are great for tying other things like bandanas. Besides just being much less likely to come undone, the square knot is symmetrical and stays aligned instead of twisting into an ugly near-vertical position like the granny knot does.
