(The plastic bits at the end can also get frayed and fall off, which happens more quickly, but I'm not sure knot style has much to do with that.)
Edit: I see it comes in clear, which would be perfect. I'll have to pick me up some of that.
Some eyelets are basically razor blades, they have very sharp edges, and tight tugging can cause wear in a very narrow spot.
Anyway it was embarrassing but it taught me a valuable lesson - shoe laces can wear out and break.
However, I remain unconvinced that the wear pattern matters this much. It seems to me that an alternative would be to re-lace your shoes every year, flipping sides. Then the pattern would be more even, too. And probably still a waste of time and effort.
