For hiking boots, I learned at some point to first tie the laces so as to make the ordinary bow, and then take one bow loop in each hand and use them to tie another overhand "knot".* As long as the original bow loops are long enough, this hugely helps to avoid the shoelaces' untying themselves. —Dan ________________ * By which I just mean making an X from the two bow loops and then putting one through the space at the bottom of the X and pulling them tight. Just like the first step in tying a bow.

Three years ago ... mathematician Ben Young showed me how to modify my five-decade-old shoelace-tying technique by doing a double-wrap where I'd normally do a single-wrap. It helps a lot. My kids (when asking me to do it for them in the morning) call it the "mathematician knot".
