I have a 75 lb puppy at home who really enjoys eating shoes. Well, not the shoes exactly, but the laces. It has happened to at least three pairs of athletic shoes. For a while, I culled laces from other shoes so I could workout. After a while, none of my shoes had laces or I had to use the same laces over and over. Obviously, I needed to end this silly untenable situation, so I googled "shoe laces" and found this company. I bought different two pairs in different styles. I like them both, but gave one pair to my wife since her shoes suffered the same fate and she wears athletic shoes to work (she is a Pilates instructor). I used these for my Nike training shoes. Normally, I would not get too excited about laces, however these are pretty cool. They look very clean, the reflective addition is nice (albeit not as bright as expected), and the quality is actually noticeably better. The tips do not fray and they maintain their color and shape. In addition, the shoes that received the upgrade had begin to show their age. These new laces breathed new life into them. They now look much better. These laces are a very worthy upgrade to the standard ones. I will buy more as I buy more athletic shoes because I think they look and feel better.
