Custom EVA Shoe Sole Materials & Midsole Solutions

Industrial EVA Shoe Sole Materials for Footwear Manufacturers

Damao Tech manufactures custom EVA shoe sole materials, injection-expanded Phylon midsoles, compression-molded unit soles, and skived sole sheets for performance running footwear, athletic sneakers, casual lifestyle shoes, and recovery sandals.

With over 20 years of experience in polymer compounding and chemical foaming, we supply raw pre-forms, wholesale sheets, and custom-tooled sole components directly to footwear brands, factory converters, and shoe component distributors worldwide.

For converters requiring flat sheet stock for die-cut insoles and wedge soles, explore our EVA foam sheet manufacturing hub or our primary custom EVA foam solutions.

Available Footwear Supply Formats

1. Injection Molded Phylon Midsoles: Ultra-lightweight (0.16–0.22 g/cm³), highly elastic, and precision-shaped through primary injection expansion and secondary thermal re-pressing. Perfect for modern performance running shoes and athletic footwear.
2. Compression Molded Unit Soles (CMP): Single-piece soles molded under heavy hydraulic pressure and heat, delivering balanced cushioning and ground-contact durability. Ideal for slides, sandals, clogs, and casual shoes.
3. Die-Cut Skived EVA Sheets: Continuous precision-sliced sheets from 1.5 mm to 30 mm thickness with tight tolerances. Used for orthotic footbeds, shoe wedges, strobel boards, and casual sneaker midsoles.
4. Compounded Raw EVA Pellets & Pre-Forms: Customized pellet blends formulated with virgin EVA, crosslinkers (DCP), chemical blowing agents, and POE/OBC rebound modifiers ready for your factory’s mold line.

Target Hardness & Performance Selection Matrix

Shoe Application	Shore C Hardness	Target Density	Mechanical Characteristics
Plush Running Midsole	40 – 46 Shore C	0.15 – 0.18 g/cm³	Maximum shock absorption, ultra-soft footstrike
Performance Trainer Midsole	48 – 53 Shore C	0.18 – 0.22 g/cm³	High energy return (> 55%), anti-fatigue resilience
Stability Medial Post	58 – 65 Shore C	0.25 – 0.30 g/cm³	Torsional resistance, over-pronation control
Single-Piece Unit Outsole	52 – 58 Shore C	0.22 – 0.28 g/cm³	Direct ground contact, balanced abrasion resistance
Occupational & Work Footbed	60 – 70 Shore C	0.28 – 0.35 g/cm³	High load-bearing support, minimal compression fatigue

Quality Verification & Footwear Testing Standards

All production batches undergo rigorous physical laboratory testing:

• Compression Set (ASTM D395): Measured at < 25% (22 hours at 23°C) to prevent premature sagging and bottoming out.
• Rebound Resilience (ASTM D2632 Test H): Verified > 55% for athletic compounds.
• Ross Flex Resistance: 50,000 cycles without cracking at both room temperature and -10°C.
• Surface Bonding Prep (SATRA TM404): Optimized for high peel strength (> 3.0 N/mm) with standard PU and polychloroprene cementing systems.
