Material Response + Cushioning
Key Features of the Popcorn ETPU Cushioning Insole
Popcorn ETPU-PU Composite
Supercritical ETPU beads and PU are foamed together to form a cushioning sheet for the heel.
SCF EVA Insole Body
SCF EVA forms the main insole body, with its grade, thickness, and geometry developed around shoe volume and target step-in feel.
EVA Arch Support
A large EVA support section reinforces the arch area while working with the SCF EVA body and heel cushioning structure.
Built Around the Complete Shoe
An insole works with the last, midsole, upper fit, and available depth. FX reviews these inputs so the construction can be assessed inside the shoe.
Application Fit
Who This Popcorn ETPU Cushioning Insole Is For
This reference is intended for teams developing running or performance-inspired shoes. It also suits everyday-comfort programs that need a responsive alternative to a basic single-foam sockliner.
Use it when energy return and cushioning are both part of the brief. Final selection should account for shoe type, fit allowance, flex pattern, and the validation plan.

Common Questions
Popcorn ETPU Cushioning Insole FAQ
What is ETPU and how is it different from other insole foams?
ETPU is expanded thermoplastic polyurethane made as fused foam beads. It supports cushioning and recovery, but the finished feel depends on bead grade, geometry, thickness, and the shoe.
Which footwear applications suit a Popcorn ETPU insole?
This reference is directed at running, performance-inspired, and everyday-comfort footwear. Check it inside the shoe because fit space, flex, and midsole construction affect the result.
Can a Popcorn ETPU insole be customized for a footwear program?
Yes. Contour, material arrangement, surface treatment, and visible design can be reviewed against your brief. Available options are confirmed during development, followed by sample evaluation.
