I ran across elastic laces while evaluating some shoes. I tried a pair and have been hooked ever since. They keep your shoes comfortably snug and make putting them on and taking them off shoes really easy, which to me is the best part. There are different design types, but the I have found that the simple elastic laces, e.g. iBungee to work equally well.  If you order laces that are too long you can easily trim them once they are installed.  I have them on all my sneakers and snow boots.
