This is one of my favorite brands of elastic laces because it comes with the clips to secure the ends of the laces. Not all of them do. You just trim to the length you want (leave a little slack for times you might want to wear your shoes looser than normal), trim, attach the dongle, and tuck your laces in near your toe box. The spring-loaded clip holds fairly well though it does eventually slip a little. I tighten mine back up every week or so. However, because the laces grip to each other, the shoe itself doesnt loosen much. Only the tongue area gets a little looser. If you have high arches or a high midfoot, you might have to use an alternate lacing method as the laces can put a little pressure on the top of your foot where the laces cross.
