I have narrow feet and find that I have a huge excess of shoe lace when tying the laces on my running shoes, even after tying a double knot. I would just cut a few inches off the laces - but I'm a bit concerned that the laces would just fray and fall apart without the plastic sheaths at the end of the laces, and that I would not be able to re-thread through the holes in the shoes. Any ideas?
As a possible solution, I'm considering elastic laces (lock laces) but I'm not sure if these will offer the necessary support for running a marathon. Does anyone have experience with these? Are they suitable for long-distance running?
What do the pros use? - I've never seen an elite athlete stopping to re-tie their laces...
