I favor a technique I was taught by a nursing student almost 30 years ago. You basically use the usual technique but each time the lace crosses another do it one extra time.

So first you wrap one lace around the other and pull it tight, well before you pull it tight wrap it around one more time. This helps hold the laces tight for the next step where you fold the laces and wrap them around each other. Do that a second time as well before you pull it fully tight.

Without video or illustration I suspect this is not easy to follow. Oh well.
