EVA Sole Manufacturer for Footwear Brands & OEMs
Firefox Foam offers EVA sole solutions for footwear applications where lightweight cushioning, flexibility and design requirements matter. Explore material and design options for sandals, slippers, casual footwear and other suitable shoe styles.
EVA Soles for Different Footwear Applications
The right EVA sole depends on footwear construction, intended use and target performance. Our product options can be evaluated according to your design, material and production requirements.
EVA Sandal & Slipper Soles
Lightweight sole solutions for everyday casual footwear, with design options for different thicknesses, shapes and surface patterns.
EVA Shoe Midsoles
Cushioning components designed to support comfort and reduce footwear weight. Material selection should consider firmness, compression recovery and the requirements of the complete shoe.
Custom-Moulded EVA Soles
Application-specific sole shapes developed around approved drawings, reference samples or footwear designs, subject to tooling and production capabilities.
EVA Sole Components
Selected EVA components can be developed for integration with other footwear materials, depending on bonding requirements and shoe construction.
EVA Midsole vs. EVA Outsole
EVA can be used in different parts of a shoe, but performance requirements are not the same.
EVA Midsole
Designed primarily for cushioning and comfort. Key selection factors include weight, firmness, compression recovery, and intended support level. Typical density: 120–250 kg/m³, hardness: 35°–55° Shore C, compression set <15%.
EVA Outsole
Designed for direct ground contact where applicable. Buyers should assess abrasion resistance (DIN abrasion typically <250 mm³), traction, surface design, and durability under intended conditions. Typical hardness: 55°–75° Shore C for enhanced wear resistance.
One-Piece EVA Sole
Combines midsole and outsole functions in a single component, commonly used in selected sandals, slides, and casual footwear.
EVA Sole Moulding & Production Methods
Compression Moulding
A prepared EVA compound or preform is shaped in a mould under controlled heat and pressure (typically 150°C–180°C, 5–15 MPa). This process suits selected sandal soles, unit soles, and custom-shaped footwear components.
Injection Moulding
EVA compound is injected into a mould to produce repeatable shapes with consistent density and dimensional accuracy. Depending on process and equipment, injection moulding supports higher-volume production with cycle times as low as 60–120 seconds per part.
Secondary Moulding & Finishing
Some designs require additional moulding, trimming, surface treatment, or finishing to achieve intended dimensions and appearance—tolerances are typically held within ±0.5mm.
Balance Cushioning, Rebound and Long-Term Support
A comfortable EVA sole requires more than a soft initial feel—we help you balance multiple performance characteristics together.
Cushioning: We evaluate how the sole absorbs loading during walking or other intended activities, with typical energy absorption of 40%–60% depending on density and hardness.
Rebound: We consider how the material responds after compression and returns toward its original shape, with rebound resilience typically 40%–55%.
Compression Set: We assess permanent deformation after sustained compression under defined test conditions—typically <15% after 22h at 50°C.
Weight & Firmness: We balance lightweight construction (density 120–250 kg/m³ for midsoles) with the support required by the shoe design, ensuring neither excessive weight nor insufficient firmness compromises performance.
Custom EVA Sole Development for OEM Projects
Developing a new EVA sole requires alignment between product design, material properties, and manufacturing constraints. We review project requirements based on our available production capabilities, including:
Design & Dimensions
Technical drawings, reference samples, sizes, and sole geometry.
01
Material Performance
Target hardness, density, cushioning, and compression recovery.
02
Appearance
Colour, tread pattern, surface texture, and branding requirements.
03
Tooling & Volume
Expected order quantity, size range, and tooling considerations.
04
Product Validation
Sample review and agreed performance checks before production approval.
05
Quality Checks for EVA Sole Production
We ensure consistent sole quality through strict control of both physical properties and finished-part dimensions.
Dimensional Checks: We verify sole length, width, thickness, and critical design features—typically within ±0.5mm tolerance.
Material Testing: We evaluate density (120–250 kg/m³), hardness (35°–75° Shore C), and compression recovery (compression set <15%) against approved specifications.
Appearance Inspection: We check colour consistency (Delta E <1.0), surface defects, moulding marks, and edge finish under controlled lighting.
Performance Validation: We conduct applicable abrasion (DIN <250 mm³), bonding (peel strength ≥4.0 N/mm per ISO 20344), and other tests according to the product's intended use.
