CONSTRUCTION
Popcorn Foam Body and Bonded Outsole
We use ETPU as the trade name for this popcorn foam shoe sole construction. EVA particles are physically expanded, then the foam beads are joined and press-formed into the sole body. The visible bead texture gives it the popcorn name.
Choose the tread and ground-contact layer for your sneaker sole unit. TPR or rubber is bonded beneath the foam body, depending on the design. Confirm availability for your selected model.

BUYER QUESTIONS
ETPU Popcorn Shoe Sole FAQ
What is an ETPU popcorn shoe sole?
It is an assembled shoe sole unit. SANSD uses ETPU as the trade name for this popcorn-style construction. The molded body starts with physically foamed EVA particles, and the ground-contact outsole is a separate bonded layer.
What does popcorn outsole mean in a shoe sole listing?
Suppliers may use popcorn outsole to describe a sole with a visible bead texture. On our assembled sole unit, that texture comes from the EVA foam body. A separate bonded TPR or rubber layer is the ground-contact outsole.
How does an ETPU popcorn sole unit differ from a compression molded EVA midsole?
An EVA foam midsole is the cushioning layer between the upper and the outsole. A compression molded EVA midsole is shaped in a mold under pressure. Our assembled sole unit pairs a press-formed body made from physically expanded EVA beads with a separate TPR or rubber outsole bonded underneath.
Can I request an ETPU midsole or a complete shoe sole unit?
Tell us whether you need a standalone midsole or a complete shoe sole unit. If your specification says ETPU midsole, include the required polymer and construction. The ETPU popcorn soles shown here use physically foamed EVA particles for the sole body and a separate bonded TPR or rubber outsole.
What outsole materials are available?
TPR and rubber are available depending on the design. Confirm the ground-contact material for your selected model.
Can I choose from existing designs?
Yes. Start with the 3D, Combo or Shell Bottom Series shown above and include a model reference in your inquiry.
Can I send my own drawing or sample?
Yes. If you are sourcing custom sneaker outsoles or assembled sole units, send a drawing, reference photo or physical sample. We will review the geometry, target sizes and tread requirements with you.
How long do samples and bulk production take?
Typical lead times are 15 days for samples and 35 days for bulk production. Lead times may vary during peak season.
Can I buy ETPU popcorn foam sheets separately?
Yes. Unshaped ETPU popcorn foam sheets are available separately for buyers who plan to press-form parts themselves.
Can you share test documentation?
Tell us the destination market, requested test standard and model so we can confirm what documentation applies.
