PORON® Foam – Advanced Cushioning Material for High-Performance Insoles

PORON® Foam is a high-performance microcellular polyurethane material widely used in advanced cushioning applications.

As a professional custom insole manufacturer, we integrate PORON® into high-end sports insoles, orthotic insoles, and comfort footwear solutions.

What Is PORON® Foam?

PORON® is a microcellular urethane foam developed by Rogers Corporation, known for its extreme durability and superior energy absorption performance.

Unlike conventional foam materials, PORON® features:

• Uniform microcellular structure
• High density with excellent flexibility
• Long-term performance stability

👉 It is engineered specifically for impact protection and medical-grade cushioning applications.

Key Properties of PORON® Foam

🔹 Excellent Shock Absorption

PORON® absorbs and disperses impact energy effectively, significantly reducing repetitive stress on the foot joints.

👉 Ideal for high-impact activities like running, basketball, and cross-training.

🔹 Extremely Low Compression Set

One of PORON’s biggest advantages is its ability to retain shape and thickness after repeated compression (it won't "bottom out").

👉 This ensures long-lasting cushioning performance compared to standard foams.

🔹 High Resilience & Energy Return

• Maintains elasticity throughout the product's lifespan
• Recovers instantly after each impact

👉 Provides consistent comfort and responsiveness during long-term use.

🔹 Durability & Stability

PORON® does not easily crack, crumble, or degrade under sweat and stress.

👉 Suitable for demanding work and athletic environments.

🔹 Wide Range of Densities

Available in various formulations:

• Ultra-soft: Slow rebound for pressure relief
• Firm: For high-energy return and support

👉 Enables flexible, targeted insole design.

Why PORON® Is Ideal for Insoles

PORON® is the gold standard for premium footwear cushioning:

✔ Long-Lasting Cushioning

Unlike EVA or standard foam which loses its bounce quickly:

👉 PORON maintains over 95% of its performance even after millions of cycles.

✔ Impact Protection

Effectively helps reduce:

• Heel impact shock
• Joint stress and knee pain
• Foot fatigue during standing or walking

✔ Thin but High Performance

PORON delivers exceptional cushioning even in thin layers (1.5mm - 3.0mm).

👉 Ideal for low-profile performance footwear where space is limited.

Applications in Insole Manufacturing

🔹 Sports Insoles

• Running & Athletics
• Training & Gym
• High-impact court sports

🔹 Work & Safety Insoles

• Long standing hours
• Industrial and military footwear

🔹 Orthotic & Diabetic Insoles

• Additional cushioning layer for sensitive feet
• Localized pressure relief support

PORON® vs EVA Foam

👉 PORON is typically used in high-performance or medical-grade insoles, while EVA is favored for general casual applications.

Typical Insole Structure with PORON®

👉 Common multi-layer construction:

• Top layer: Anti-microbial fabric / breathable foam
• Mid layer: PORON cushioning (Impact zone)
• Bottom layer: EVA base or TPU arch support

👉 This combination creates a perfect balance of comfort, support, and durability.
