Material selection and structural design are important considerations in sports insole manufacturing. EVA density, cushioning zones, and arch support all influence the construction of a finished insole. For footwear brands and orthotic product suppliers, a well-designed material combination also creates more options for product development.
IDEASTEP KS3100 sport insoles combine polyester fabric, perforated cushioning EVA, and a dual density structure. The design features higher-density EVA at the arch and a cushioning pad at the heel, making it a suitable option for manufacturers and wholesalers developing sports insole product lines.

Dual Density EVA in Sports Insole Manufacturing
Dual density EVA allows different material densities to be incorporated into specific areas of an insole. Instead of using one uniform material throughout, manufacturers can select different density configurations according to the structural requirements of each section.
In the KS3100 design, the forefoot and heel feature dual density EVA, while higher-density EVA is used in the arch section. This multi-zone construction provides a differentiated material layout for sports footwear and orthotic product development.
EVA is widely used in footwear components because it can be processed into different shapes and structures. Its density, thickness, and placement can be specified according to the intended product design.
Key Structural Features of KS3100 Sport Insoles
The KS3100 combines several material and structural elements to create a multi-zone sports insole.
Higher Density EVA Arch Support
The arch section uses higher-density EVA to provide a more structured support area. This construction is relevant to manufacturers developing sports insoles and arch support product ranges.
Dual Density Forefoot and Heel
The forefoot and heel incorporate a dual density EVA design. Different density characteristics in these sections allow manufacturers to specify distinct material configurations within one insole.
Perforated EVA Cushioning and Heel Pad
Perforated cushioning EVA forms part of the insole construction, while a dedicated heel pad adds another cushioning component to the design.
These features give product developers more options when selecting EVA materials and structural configurations for sports footwear applications.
Breathable Fabric and Moisture Management
KS3100 combines polyester fabric with a breathable mesh surface. The textile upper complements the EVA structure and provides a material option for sports insole collections.
The product is also specified with moisture-wicking and odor-control functions. For projects requiring verified performance, buyers should confirm the relevant material specifications and supporting test documentation before making detailed technical claims.
Applications in Footwear and Orthotic Product Development
The KS3100 structure can be considered for several B2B product categories.
Sports Footwear Manufacturing
Footwear manufacturers can evaluate this design for sports shoe collections requiring EVA cushioning, a structured arch section, and textile surface materials.
Orthotic Insole Product Ranges
Orthotic manufacturers and laboratories may consider the higher-density EVA arch section when developing insole products with different support configurations. Final suitability depends on the required dimensions, material densities, and overall construction.
Private Label Sports Insoles
For footwear brands and distributors, customized sports insoles provide an option to develop product lines with specific material and appearance requirements. KS3100 offers customized color options, with OEM and ODM cooperation available for suitable projects.
What to Consider When Sourcing Sport Insoles
When evaluating a sports insole supplier, B2B buyers should review the following specifications:
- Material Composition: Confirm the polyester fabric, mesh surface, and EVA material configuration.
- Density Distribution: Check the density arrangement in the forefoot, heel, and arch sections.
- Structural Details: Review the perforated EVA, arch support section, and heel cushioning pad.
- Customization: Discuss color and other product requirements for private-label projects.
- Packaging and Supply: Confirm packaging formats, sample arrangements, and bulk order requirements.
For OEM and ODM projects, sample evaluation helps verify material combinations, dimensions, and product finish before bulk production.
