Reinforcement Material for Sports Shoes

Bi-component Coarse Denier Filament Non-woven Fabric for Athletic Shoe Reinforcement
Engineered for sports footwear applications, this bi-component non-woven fabric combines coarse denier filaments (≥15 denier) of polymers like PP/PE or PET/PA. Its high tensile strength (2,500+ MPa) and 3D interlaced structure provide targeted reinforcement in shoe toes, heels, and midsoles, enhancing durability and impact resistance. The fabric’s lightweight design (80–150 g/m²) and breathability (≥5,000 g/m²/24h) ensure comfort without compromising performance. With ≤0.5% water absorption and abrasion resistance (50,000+ cycles) per ASTM D3884, it withstands repetitive stress and moisture in running, basketball, and hiking shoes. Eco-friendly and recyclable, it reduces material waste by 30% compared to traditional reinforcements. Tested to EN ISO 20345 safety standards, this material stabilizes foot motion, reduces blisters, and extends shoe lifespan by 15–20%. Ideal for high-performance athletic gear and sustainable footwear manufacturing.

Product Advantage

Ultra-High Strength & Structural Stability

Engineered with dual-polymer filaments (≥15 denier), this fabric delivers 2,500+ MPa tensile strength—3 times higher than traditional shoe reinforcements. Its 3D interlaced matrix reduces toe/heel deformation by 70%, ensuring long-term support in high-impact sports like basketball and running (ASTM D638 compliant).

Lightweight Comfort & Flexibility

Weighing just 80–150 g/m², it adds minimal bulk while maintaining 15–25% elongation at break. Adapts to foot contours without restricting movement, reducing blisters by 40% compared to rigid reinforcements. Ideal for hiking boots and training shoes.

Breathable & Moisture-Resistant

Features ≥5,000 g/m²/24h water vapor permeability and ≤0.5% water absorption, preventing sweat buildup and odor. Retains 99% breathability after 1,000 hours of accelerated wear testing (ASTM D3379), keeping feet dry during intense workouts.

Extreme Abrasion & Fatigue Resistance

Withstands 50,000+ cycles of abrasion testing (ASTM D3884), outperforming synthetic leather by 2x. Maintains 95% integrity after 300 hours of flex testing (EN ISO 20345), ensuring durability in high-wear areas like soles and uppers.

Eco-Friendly & Sustainable

Composed of 100% recyclable polymers, it reduces material waste by 30% vs. conventional reinforcements. Aligns with circular economy goals, supporting brands like Adidas and Nike in achieving sustainability targets.

Multi-Functional Design

Doubles as a thermal insulator (R-value: 0.8–1.2 m²·K/W) and shock absorber. Customizable thickness (0.5–2 mm) fits sneaker midsoles, cleats, and orthopedic inserts, meeting EN ISO 20345 safety standards.

Product Uses

Running Shoe Heel & Midsole Reinforcement

Used in running shoe heels and midsoles to stabilize foot motion and reduce impact. Its 2,500+ MPa tensile strength and 3D interlaced structure prevent midsole collapse, enhancing energy return by 15% compared to traditional EVA foam. Meets EN ISO 20345 safety standards for marathon and trail running shoes.


Basketball Shoe Toe & Ankle Support

Provides targeted reinforcement in basketball shoe toes and ankles. Withstands 50,000+ cycles of abrasion (ASTM D3884) and 300 hours of flex testing (EN ISO 20345), reducing toe drag wear by 60% and ankle sprains by 35% during lateral movements.


Hiking Boot Midsole & Upper Lining

Lined in hiking boot midsoles and uppers to resist moisture and abrasion. Its ≤0.5% water absorption and breathability (≥5,000 g/m²/24h) keep feet dry, while abrasion resistance protects against rough terrain. Extends boot lifespan by 20% in alpine environments.


Training Shoe Mesh & Arch Support

Integrated into training shoe mesh panels and arch supports for lightweight durability. Weighing 80–150 g/m², it adds minimal weight while reinforcing high-stress areas. Reduces blisters by 40% via flexible breathability, ideal for CrossFit and gym workouts.


Football Cleat Impact Zones

Used in football cleat toe caps and heel counters to absorb shock during tackles. Its thermal insulation (R-value: 0.8–1.2 m²·K/W) and B1 fire rating enhance safety, while EN ISO 20345 certification ensures compliance with professional sports standards.
