Sorry--there was nothing I liked about those laces. First of all, the ends were too wide to fit in the holes in the shoe without using some type of device to enlarge the hole. Once in the shoe, there is hardly any give or take with the laces, they are very stiff. With shoe laces, if your feet swell during the day and you need to open up regular laces to get your feet out of the shoe, you can do that.  With your laces, it is a major headache to loosen the laces to get your feet out. I wish I had not purchased them.
