So far so good with these laces. These are my first laces like these. I've used the draw string elastic type on my running shoes, but I wanted these for my day-to-day walking shoes. Getting them through the lace holes was a bit of a challenge due to the whole size. I am really curious how long they will last before stretching out. I have another set of shoes I am thinking of adding some of these to, but I'll wait and see what their lifespan is first.
