Let’s keep this one short—literally. Because when it comes to shoelaces, length matters.

Whether you’re replacing laces on your trail runners, walking boots, or approach shoes, the right size makes a big difference. Too short, and you’re straining to tie a knot. Too long, and you’re catching loops on rocks and brambles.

At Crib Goch Outdoor, we often help customers match the correct lace length based on eyelets (those holes the laces pass through) and the type of shoe or boot.

General Rule of Thumb Shoe Lace Length by Eyelets:

Eyelets (pairs)Lace LengthBest For
4–590–110 cmLightweight trail runners
5–6110–130 cmStandard running shoes
6–7130–150 cmLow-cut hiking shoes
7–9150–180 cmMid-ankle walking boots
9–10+180–210+ cmHigh-cut mountain boots

If you want extra lace for a heel lock or more advanced lacing techniques, go up a size.

Shoelace Tips:

  • Flat laces tend to stay tied better than round ones.
  • Kevlar or polyester laces are ideal for trail and mountain use—durable and less prone to fraying.
  • For trail runners with gaiter hooks or lace pockets (like some Altra or Inov8 models), shorter laces reduce clutter.

Still unsure? Bring your shoes into the shop or give us a ring—our staff are always happy to advise.

Your laces do more than keep your shoes on—they keep you moving comfortably and securely. Make sure they’re the right length to do the job.
