A sports insole needs to balance cushioning, impact absorption, and breathability without making the shoe unnecessarily bulky. For footwear brands and distributors, the material combination is also important when one insole needs to fit different active footwear programs.
The IDEASTEP XD-811 combines soft PU foam, Poron gaskets, and a breathable fabric upper. The PU foam provides cushioning, while the Poron components add shock absorption in key areas.
With a simple, sports-focused construction, XD-811 is suitable for running, training, sports sneakers, and other footwear programs where soft cushioning is required.

XD-811 PU Foam Insole Construction
XD-811 uses different materials for specific functions rather than relying on foam alone.
The main body is made from soft PU foam, providing the cushioning base. Poron gaskets are added for shock absorption, while the fabric upper provides a breathable surface.
Soft PU Foam
The PU foam gives the insole a soft and cushioned feel underfoot. Its flexible construction makes it suitable for sports shoes as well as casual athletic footwear.
Poron Shock-Absorbing Gaskets
Poron gaskets are incorporated into selected areas to provide additional shock absorption. This gives the insole a more functional construction for footwear exposed to repeated movement and impact.
Cushioning and Breathability
The combination of PU foam and a breathable fabric upper keeps the construction focused on two practical requirements: underfoot cushioning and in-shoe comfort.
The fabric surface supports airflow around the foot, while the foam provides a softer base during everyday movement and sports activities.
Together, these materials make the insole suitable for footwear programs where both cushioning and breathability are part of the product specification.
Applications for Sports Footwear
The construction is suitable for several footwear categories.
Running and Training Shoes
Running and training shoes require cushioning that can accommodate repeated movement. The soft PU foam base and Poron components make this insole suitable for these applications.
Sports Sneakers
For sports sneakers and casual athletic footwear, the softer cushioning profile can be used where comfort is a key product requirement.
Sports Insole Product Lines
For wholesalers and distributors, XD-811 can also be included as a cushioning-focused SKU within a broader insole range.
Its material specification is straightforward: PU foam for cushioning, Poron for shock absorption, and breathable fabric for the upper.
XD-811 Material Structure
| Component | Function |
|---|---|
| PU Foam | Soft cushioning |

This multi-material construction gives the product more functionality than a basic single-material foam insert while keeping the overall design relatively simple.
XD-811 vs. Basic Foam Insoles
The main difference between XD-811 and a basic foam insert is the combination of materials. Instead of relying only on foam, the design adds Poron shock-absorbing components and a breathable fabric surface.
| Feature | XD-811 | Basic Foam Insole |
|---|---|---|
| Main Material | PU Foam | Foam |
| Cushioning | Soft PU Foam | Depends on material |
| Shock Absorption | Poron Gaskets | Depends on design |
| Upper Surface | Breathable Fabric | Depends on construction |
| Sports Application | Yes | General |
| Customization | Available | Depends on supplier |
For buyers looking for a ready-made option with both cushioning and shock absorption, this construction provides a practical starting point.
Wholesale and OEM Options
XD-811 can be supplied for wholesale sports footwear programs as well as selected OEM projects.
For brands developing their own insole or footwear range, customization requirements such as color, branding, packaging, and product specifications can be discussed according to the project.
The existing construction also gives buyers a starting point for evaluating samples before moving into larger production requirements.
