Footwear Applications
Heavy-Duty Work & Safety Boots (1.75–2.5 mm)
Designed for heavy-duty steel shank insertion, puncture-resistant sole assemblies, and heel-nailing retention.
Outdoor Trekking & Athletic Footwear (1.5–2.0 mm)
Engineered for cold-bonded running shoes, trail runners, and hiking boots requiring high flex fatigue resistance (SATRA PM3).
Formal Leather & Casual Cemented Shoes (1.25–1.75 mm)
Delivers high dimensional stability and edge-beveling performance for traditional cemented, Strobel-stitched, and Goodyear welted constructions.
Children's & Lightweight Comfort Shoes (1.25–1.5 mm)
A lightweight, low-density variant configured for flexible juvenile footwear and flexible casual flats, providing adequate cushioning while maintaining low structural weight.
Customization Options
Available from 1.25mm to 2.5mm with a consistent industrial tolerance of ±0.1mm for accurate shoe weight management.
Supplied in standard 1.0m x 1.5m sheets or precision-slitted strips ready for automatic lasting feeders.
Custom inner board dyeing based on Pantone codes or physical color swatches.
Custom roll printing for brand logos, thickness gauges, and lasting alignment guides using non-bleed latex inks.
Adjustable flex stiffness via specialized binder resins, with optional micro-pinhole perforation for enhanced breathability.
Manufacturing Process
Fiber Carding & Needle Punching: Automated mechanical fiber blending builds uniform GSM web density.
Acrylic Resin Impregnation: Full-immersion bath saturates the fiber matrix to prevent delamination during shoe lasting.
Thermal Drying & Curing: Multi-zone heat tunnels cure the binder to lock in structural rigidity.
Precision Calendering: Heated steel rollers compress the sheet to precise thickness tolerances within ±0.05mm.
Automated Slitting: Inline equipment trims boards to target sheet dimensions for direct factory feeding.

FAQ
Q: What is the difference between a nonwoven insole board and a paper insole board?
A: A nonwoven insole board offers better flexibility, moisture resistance, and dimensional stability. It is more suitable for footwear requiring repeated bending and longer wearing comfort.
Q: How do you support quality audits from international footwear brands?
A: Factory quality documents, production records, material traceability, and audit-related documents can be provided for third-party inspections such as SMETA and BSCI verification.
Q: How does this nonwoven insole board perform in high-humidity environments?
A: The polyester fiber structure maintains dimensional stability better than many natural fiber boards when exposed to moisture. Under normal footwear conditions, thickness change remains controlled after humidity exposure testing.
Q: Can you provide customized insole boards for specific shoe manufacturing requirements?
A: Yes. Custom options include thickness adjustment, density modification, color matching, logo printing, and perforation design according to footwear production requirements.
Q: How do you ensure thickness consistency during mass production?
A: Production batches are controlled through automatic thickness measurement and sampling inspections. Each batch is checked for thickness tolerance, density consistency, and bonding strength before shipment.
