I've noticed that a lot of liners' laces aren't very strong. I ended up changing out mine with some laces that were in an older pair of Celcius I had (they were surprisingly high quality). But before I swapped them out I searched around to see what I could find and came across some good quality lacing at a seemstress shop. The only reason I didnt get it at the time was because I didnt have the original laces with me to get the length and they wouldn't have the wax or taped ends that would make it easier to thread through the quick lace system. It would have worked perfectly though had I opted to go with it. There is stuff out there just shop around.
