Waxed flat shoelaces by LACCICO are available in widths of 3 mm, 4 mm, and 6 mm, offering an optimal balance of a flat profile, tear resistance, and a modern aesthetic.


While the slim 3 mm (F3) and 4 mm (F4) variants are ideally suited for elegant dress shoes, brogues, and classic sneakers, the substantial 6 mm editions (F6 / F6-XR) are perfectly matched with casual sneakers and rugged boots.

Waxed flat shoelaces provide better and more stable hold on premium sneakers primarily because they significantly improve the interplay of friction, knot tension, and flat surface contact.


The flat profile rests broadly against the tongue, distributing pressure evenly across the instep, while deep paraffin wax saturation reliably maintains set tension and ensures the lace remains dimensionally stable in humid conditions.

For sporty, elegant sneakers and smart casual shoes, waxed flat shoelaces with a 4 mm width (F4-CS series) are the ideal choice.


The 4 mm width bridges the gap between formal dress laces and heavy sneaker laces: it rests flat across the tongue to distribute pressure evenly, protects delicate smooth leather, and guarantees complete edge stability and dimensional shape retention thanks to its dense cotton braid.

Twisting of flat shoelaces is prevented through two-handed guidance during threading, utilizing the eyelet rim as a stabilizing guide rail.


While one hand pulls the aglet end evenly, a finger of the other hand applies slight counter-tension within the loop; deep wax saturation and dense circular braiding impart the necessary torsional rigidity to ensure the lace stays completely flat across the tongue.

Technical Expertise for Your Style: Waxed Flat Laces in Width Comparison

Available in widths of 3 mm, 4 mm, and 6 mm, our waxed flat shoelaces provide dimensionally stable guidance for any footwear style. Densely produced on modern rotary braiding machines without synthetic hollow cores and refined through deep wax saturation, the edges stay true to shape, repel water, and resist mechanical friction.

3 mm Flat | Series F3-CS

Filigree Understatement for Business & Derbys

The narrow 3 mm variant is the secret for shoes with delicate blind eyelets (2.0 to 3.0 mm). Breaking deliberately with the convention of classic round laces, it lends formal dress shoes, brogues, and Goodyear-welted derbys a subtle, elegant flat-edge aesthetic without adding bulk.

4 mm Flat | Series F4-CS

Smart-Casual for Leather Sneakers & Chukkas

Offering the ideal balance between elegance and athletic profile at 4 mm wide: specially engineered for classic smooth leather sneakers, court silhouettes, and low shoes with punched eyelets from 3.5 mm. Guarantees flat contact on the tongue and even pressure distribution.

6 mm Flat | Series F6-CS & F6-XR

Sporty Presence for Retro Sneakers & Boots

Tailored for bold silhouettes: as F6-CS, the satin-sheen classic for voluminous retro and skate sneakers; as F6-XR, extra densely braided with a soft-solid feel for maximum tensile strength in rugged heritage boots and workwear styles.
