The most important part of the instructions is about cutting the laces after you have the slider on. It says leave 2 inches. No! No! Remember you can always cut shorter if too long yet if they are cut too short too start with you will require more laces. Leave at let inches to start with. I like the laces and it does make the shoes easier to get in and out of. I will purchase more and from this seller. Now Im out the door for my ten mile run....hmmm
