Lacing System

The lacing system is the closure mechanism that allows the shoe to be tightened around the foot. It includes the laces, the eyelets (or hooks, dials, speed-lacing hardware), and the facings (the reinforced panels that the eyelets are mounted on). Eyelet pull-out — when the eyelet tears through the facing under lace tension — is the primary lacing-system failure mode, and the standard QC test is 80N pull-out force per eyelet. The lacing system determines fit adjustability, ease of entry, and 3-5% of FOB cost.

Eyelet, Hook, and Dial Hardware

Three closure hardware types dominate: Eyelets (the standard, 5-8mm diameter metal or plastic ring mounted through a hole in the facing, the lace passes through the ring): dress (5-7 eyelets), casual (5-6), athletic (6-7), work and hiking (6-8). Hooks (open metal hooks, no ring, faster lacing): the top 1-2 positions on athletic and work boots, sometimes all 6 positions on tactical boots. BOA dial (a stainless steel or polymer dial that tightens a steel cable or textile lace, push-button release): cycling, golf, some hiking and work. Cost $4-8 per dial system vs. $0.30-0.80 for a full eyelet set. The 2026 trend is hybrid systems (eyelets at the bottom, BOA at the top, used in road cycling and running).

Eyelet Material: Brass, Nickel, Plastic

Brass (premium, $0.04-0.10 per eyelet): the heritage choice. Does not rust, holds shape, allows for plating (nickel, antique brass, black oxide). Standard in quality dress shoes. Nickel-plated steel (mid-tier, $0.02-0.05): the standard in 80% of mass-market and athletic. Stronger than brass, lighter, cheaper. Plating can wear off after 12-24 months. Plastic (mass-market, $0.005-0.02): the standard in disposable athletic and children's. Prone to cracking under cold (below -10°C) and under high lace tension. The eyelet pull-out test (80N) is most often failed by plastic eyelets, especially after aging.

The 80N Pull-Out Strength Test

The industry-standard QC test for eyelets: a calibrated force gauge pulls the eyelet perpendicular to the facing at a fixed rate (50mm/min) until the eyelet pulls through or the facing tears. The passing threshold is 80N per eyelet for casual and dress, 100-120N for athletic and work (because athletic laces can be tensioned to 30-50N per lace in use, and the eyelet must hold 2-3x that under spike loads). Premium eyelets (brass, properly set on a reinforced facing) test at 150-200N. Plastic eyelets on a non-reinforced facing often fail at 30-50N, which is why they tear out in use.

The 4 Sourcing Questions for Lacing Systems

  1. What is the hardware type and material (brass eyelet, nickel-plated steel, plastic, BOA)?
  2. What is the eyelet pull-out strength on production lots (target 80N+ dress, 100N+ athletic)?
  3. How many eyelets/hooks and what is the spacing (typically 18-22mm dress, 22-28mm athletic)?
  4. Is the facing reinforced (a separate piece under the eyelet) and what is its material?

Laces, Hardware, and 2026 Trends

Laces themselves are a $0.10-0.50 per pair component, often cotton-wrapped polyester for dress and round or oval polyester for athletic. Premium laces are waxed cotton or Kevlar-reinforced. Hardware (eyelets, hooks, dials) is sourced from China, Italy (for premium brass), and the US (BOA is US-based). The 2026 trend is the speed-lacing system (a thin cord that runs through channels in the upper, tightened by a single pull and secured by a toggle, used in Nike FlyEase and adaptive footwear for seniors and disabled users).
