Rope Lace Thickness: If you're unsure, 10mm is the right choice. The difference from 6mm.

Laces aren't consumables. Their thickness determines the silhouette. To get straight to the point, there's a reason HYPELACE offers only 10mm.

Thickness changes both appearance and ease of tying

Unlike flat laces, the "thickness" of rope laces directly translates to volume. The same shoe can look elegant with thin laces or rugged with thick ones. If you choose this without much thought, it will look out of place the moment you put them on.

6mm	Slender. While there's less stress on existing eyelets, it's a limited choice. It doesn't clash with low-cut running shoes, but it's unlikely anyone will notice you've "changed your laces." The risk of it just looking like the original laces is higher.
10mm (HYPELACE)	Maximum volume. Excellent compatibility with AF1s and high-top sneakers, this thickness makes it immediately obvious you've "changed your laces." The knots maintain their shape without flattening, so you can wash and reuse them repeatedly. If you have no reason to hesitate, choosing this from the start will not lead to failure.

Round laces vs. flat laces are entirely different matters

Separate from thickness, the cross-sectional shape also affects the appearance. Round laces create a three-dimensional look with a strong presence, while flat laces give a flat, subdued impression. Rope laces are primarily designed as round laces, which is the premise for creating a look that is "complete with just the laces." If you're looking for the subdued nature of flat laces, you're in the wrong category to begin with.

Which one to choose if you're unsure?

To be honest, the only reason to choose 6mm is if you "deliberately don't want to make a statement." If you have low-cut shoes and don't want to draw attention, then 6mm. Everyone else – meaning those who want to convey that they've "changed their laces" or want to replace them before buying new shoes – should choose 10mm. If you're hesitating, the answer is already 10mm.

Why HYPELACE offers only 10mm

Instead of broadening options, we focused on a specific target. If you treat rope laces not as "a type of accessory" but as "an essential part for completing a shoe," then they need to be a thickness that makes an impact. While 6mm can also make a statement through its thinness, that's almost synonymous with choosing "not to make a statement." HYPELACE deliberately avoids that. 10mm fits AF1s perfectly and is a size that clearly communicates that you've "changed your laces." Even if we expand our categories in the future, we won't compromise on this standard.

Conclusion

Thinness is the choice "not to make a statement." Thickness is the choice "to make a statement." Before you buy new shoes, swap your laces for 10mm first.
