Sampling is where most delays happen — not because factories are slow, but because feedback loops are unclear. Use this stage gate with your OEM partner.
Stage 1 — Proto / development sample
Built to prove construction: foam stack, cover hand-feel, logo placement. Expect 5–7 days for standard platforms when materials are in stock. Custom molds add tooling time.
Stage 2 — Fit & wear sample
Test in the actual shoe last or retail shoe model. Check heel slippage, arch fill and edge thickness. Document feedback with photos and annotated size notes.
Stage 3 — Pre-production (PP) sample
Made with bulk materials and packaging artwork. This becomes the golden sample locked against the PO. Do not change foam suppliers after PP without a new approval.
Stage 4 — Bulk & AQL
Production typically runs 7–15 days after deposit and PP approval. Agree inspection criteria before cutting starts.
Buyer tips that save weeks
- Approve packaging artwork in parallel with physical samples.
- Consolidate comments into one response per stage.
- Keep one spare PP sample sealed for future QC disputes.
