Ive always had a problem with my laces wearing out very fast on my wading boots. Brushwacking just kills them. I would think you guys tromping through the heather have the same problem? The banks on my local waters are filled with briars's which killed 4 pairs of laces last year. I went to the local engineering supply outlet and bought a pair of kevlar laces. There super tough and cut resistant. Last year my second trip out and my laces were frayed. Have walked quite a bit through that knarley stuff this year and laces are still like new. Just something I thought I would pass on
Theres used for safety wear.Some high end hiking boots have them as well.
