I've replaced laces in several pairs of trail runners with Lace Lab laces. They last forever. What I really like is that for some reason I don't have to snug them as tight as regular laces. The laces that come with the shoes have to be tied tighter than these. I can get them to the perfect place and they don't loosen at all. Since I have a Morton's neuroma, keeping shoes a bit looser is great. I always replace my laces with Reflective Rope Laces. 54" laces are a bit long but I double tie them and they are fine.
