Footwear manufacturing relies heavily on specialized polymer materials that provide comfort, durability, flexibility, and grip. From sports shoes and sandals to industrial safety footwear, selecting the right polymer grade directly affects product performance and user comfort.

At Source, India’s industrial raw material ecosystem for polymers, chemicals, additives, and sustainable materials, footwear manufacturers can compare and source polymer grades used in shoe soles, midsoles, and molded footwear components.

This guide explains the key polymer grades used in footwear manufacturing, including EVA, PVC, and POE, along with their properties, applications, and how manufacturers choose between them.

What Polymers Are Used in Footwear Manufacturing?

Modern footwear production uses several polymer materials depending on the required balance of comfort, durability, and cost.

Common Polymers Used in Footwear

• EVA (Ethylene Vinyl Acetate)

• PVC (Polyvinyl Chloride)

• POE (Polyolefin Elastomer)

• TPR (Thermoplastic Rubber)

• PU (Polyurethane)

Among these, EVA and PVC dominate mass footwear manufacturing, particularly for soles and molded sandals.

How to Choose the Right Polymer Grade for Footwear

Selecting the right material depends on several technical and commercial considerations.

1️⃣ Comfort & Cushioning

Running shoes and sports footwear require high cushioning and shock absorption.

2️⃣ Weight

Lightweight footwear improves user comfort and reduces fatigue.

3️⃣ Flexibility

Flexible soles improve walking comfort and durability.

4️⃣ Cost Considerations

PVC is generally cheaper, while EVA offers higher comfort but at a higher cost.

5️⃣ Slip Resistance

Anti-slip performance is critical for both sports footwear and safety shoes.

Comparison of Footwear Sole Materials

EVA is widely preferred for comfort-driven footwear, while PVC is commonly used for low-cost molded footwear and sandals.

EVA (Ethylene Vinyl Acetate) in Footwear Manufacturing

What is EVA?

EVA is a copolymer of ethylene and vinyl acetate. The presence of vinyl acetate provides softness, elasticity, and cushioning properties, making EVA one of the most widely used materials for footwear soles.

Why EVA is Used in Shoe Soles

EVA is highly valued in the footwear industry due to its balance of flexibility, cushioning, and lightweight characteristics.

Key Advantages

• Lightweight material

• Flexible and comfortable

• Waterproof

• Good shock absorption

• High friction for anti-slip performance

• Excellent cushioning

Common Applications

EVA is widely used in:

• Sports shoe soles

• Sandals and slippers

• Running shoes

• Midsole cushioning layers

• Kids footwear

EVA Vinyl Acetate Content Used in Footwear

The softness and flexibility of EVA depend on the percentage of vinyl acetate.

Common EVA Grades

Higher vinyl acetate content generally provides greater softness and elasticity.

PVC (Polyvinyl Chloride) in Footwear Manufacturing

PVC is another commonly used polymer in molded footwear, particularly where cost efficiency is important.

Why PVC is Used

PVC footwear is commonly used for:

• Low-cost sandals

• Rain footwear

• Industrial footwear

• Casual molded shoes

Key Properties

• Durable material

• Good abrasion resistance

• Lower raw material cost

• Easy to process in injection molding

However, PVC soles tend to be heavier and less flexible compared to EVA.

What is POE Used For in Footwear?

Polyolefin Elastomer (POE) is commonly blended with EVA to improve mechanical and comfort properties.

Why POE is Mixed with EVA

Footwear manufacturers blend POE with EVA to:

• Increase softness

• Improve bounce-back performance

• Enhance anti-slip properties

• Improve flexibility

POE acts as a performance modifier, improving comfort and durability in sports and premium footwear.

Comparison of Footwear Polymer Performance

Blending EVA with POE allows manufacturers to produce premium comfort footwear without sacrificing durability.

Frequently Asked Questions about Footwear Polymer Grades

Which polymer is commonly used in shoe soles?

EVA (Ethylene Vinyl Acetate) is one of the most widely used polymers for shoe soles because it is lightweight, flexible, and provides excellent cushioning.

Which EVA percentage is used in footwear?

Footwear manufacturers commonly use EVA grades with 18% or 28% vinyl acetate content, depending on the required softness and flexibility.

Is EVA better than PVC for shoes?

Yes. EVA is generally considered better for comfort and cushioning, while PVC is used for lower-cost footwear.

Why is POE added to EVA?

POE is blended with EVA to improve softness, flexibility, and bounce-back performance in footwear soles.

Which material is cheaper for footwear soles?

PVC is usually cheaper than EVA, which is why it is commonly used for budget footwear products.

Can EVA soles be used for sports shoes?

Yes. EVA is widely used in sports shoes because it offers cushioning, shock absorption, and lightweight performance.
