When I wear my bike shoes to work the laces would come undone all the time. Mostly because I sit in my chair in a way where my feet sort of cross under my chair and rest on a leg of the chair. It would mess up my knots. I even got to the point where I was double knotting them. I saw this vid a while back and never really thought about it. Well this week I started tying my shoes this way and it totally works. They last all day long.
