Cloud Replacement Lace Buying Guide
Cloud replacement laces are the aftermarket cord or flat laces designed to fit On Running Cloud-series sneakers, where the primary trade-off is lace diameter versus eyelet geometry and the loop-lock hardware. The decision rule is simple: match the lace profile (round 2.5-3mm cord vs flat 7-8mm) to your exact Cloud model's eyelet count and whether you use the speed-lace loop, not just the shoe's colorway.
Lace Profile:Round 2.5-3mm cord / flat <=7mmLength by Eyelets:5 pairs: 45-50cm / 6 pairs: 55-60cmSheath Material:Polyester or poly-cotton, 16+ strandLock Compatibility:Low-stretch cord for speed-loop models

Highlights
- On Cloud models use either 5 or 6 eyelet pairs, and lace length must scale accordingly: 45-50cm for 5-eyelet low-profile models, 55-60cm for 6-eyelet versions.
- Round cord laces at 2.5-3mm diameter are the standard for Cloud eyelets; flat laces above 8mm width will bunch and resist the narrow punched eyelets.
- Speed-lace models with a rear loop lock require a lace with a firm, low-stretch core (polyester or Dyneema blend) so the loop tension holds under running load.
- Abrasion resistance comes from the sheath weave: 16-strand or higher polyester sheath outlasts 8-12 strand cotton-blend cord on concrete and gym floors.
Best use cases
- Best fit: pick 45-50cm round 2.5mm polyester laces for Cloud 5 and Cloud X with 5 eyelet pairs and no loop lock; skip flat 10mm laces that won't thread cleanly.
- Best fit: choose 55-60cm low-stretch cord with a firm aglet for Cloudstratus or Cloudmonster 6-eyelet models if you run and need the loop to stay tight; skip cotton laces that stretch when wet.
- Wrong fit: don't buy one-size 'universal' 120cm laces for Cloud sneakers — the excess length doubles over the tongue and defeats the low-profile fit; trim or select the correct short length.
- Wrong fit: avoid waxed dress-shoe laces on Cloud models; the wax clogs the narrow eyelets and the slick finish lets the loop lock slip during activity.
Buying tips
- Count your eyelet pairs before ordering: 5 pairs → 45-50cm, 6 pairs → 55-60cm; add 5cm if you prefer a visible bow over a tucked loop.
- Match lace diameter to eyelet size: 2.5-3mm round cord for standard Cloud eyelets; 3.5mm only if the eyelet is visibly enlarged or reinforced.
- Choose a polyester or poly-cotton sheath over 100% cotton for sneaker use; cotton absorbs sweat, stretches, and frays 2-3x faster at the aglet.
- Confirm the aglet type: heat-shrink or metal-tipped aglets survive repeated re-lacing; glued plastic tips crack and leave residue inside the eyelet channel.

What to check before buying
- Count eyelet pairs on your exact Cloud model and measure the old lace end-to-end while relaxed to confirm the replacement length within 5cm.
- Check whether your model uses a rear speed-loop or standard bow; loop-lock shoes need firm low-stretch cord, not soft cotton.
- Measure eyelet opening diameter with a ruler or caliper; if under 3mm, stay at 2.5mm round cord and avoid flat laces entirely.
- Confirm lace colorfastness for synthetic uppers: dark dyes on white cord can bleed; choose solution-dyed or pre-washed laces for light-colored Clouds.
