Start with an approved input, not a mood board
Name each sample by purpose. A first development sample can use substitute colors to check pattern and fit; a pre-production sample should use production-intent materials and processes. Confusing the two leads buyers to approve details that cannot be repeated.
The fastest projects are not the ones with the fewest documents. They are the ones where the buyer and manufacturer agree what must be true before the next stage begins.
- Revision-controlled tech pack and clear sample objective.
- Last or reference fit, base size, size range, and measurement tolerances.
- BOM with production materials, temporary substitutes, and color standards identified.
- Artwork, placement dimensions, packaging files, and test plan.
Shoe sample development workflow
Not every project needs every sample type, but skipping a gate should be a deliberate risk decision.

| Stage | Work | Required output | Approval gate |
|---|---|---|---|
| 01 | Mock-up or concept sample | Proportion and construction feasibility | Direction accepted |
| 02 | Fit sample | Base-size fit and pattern corrections | Fit comments closed |
| 03 | Material and color trials | Swatches, logo strike-offs, bonding evidence | Materials accepted |
| 04 | Development sample | Integrated wearable prototype | Construction revision approved |
| 05 | Size set | Selected graded sizes and measurements | Grading accepted |
| 06 | Pre-production sample | Production-intent shoe and packaging | Golden sample signed |
| 07 | First article | Early bulk pair from the production line | Line release |
Decisions that change cost and timing
Sample charges reflect pattern work, hand operations, special material purchase, tooling, and courier cost. Ask what is included in each round and whether any fee is credited later, but do not optimize away a sample that closes a material risk.
- Tooling dependency: New sole or hardware molds can place sample timing on the tooling critical path.
- Material lead time: Custom knit, dyed mesh, and special compounds may not be available for the earliest fit sample.
- Revision quality: Consolidated measured comments are faster than scattered subjective messages.
- Courier and duplicates: Plan enough pairs for buyer review, testing, factory reference, and inspection reference.
Common failure modes and prevention
A sample can look acceptable while still hiding bulk-production risk.
Swipe horizontally to view all columns.
| Risk | Why it happens | Prevention | Owner |
|---|---|---|---|
| Approval on substitute material | Production component was unavailable | Record every substitute and reapprove final material | Development team |
| Fit comment is subjective | No measurements or wearer context | Use marked photos, dimensions, and fit notes | Buyer product team |
| One size approved | Grading is assumed | Review a size set and critical measurements | Pattern and buyer teams |
| Golden sample altered | Reference pair is not sealed or recorded | Sign, date, photograph, and retain duplicates | Both parties |
Approval records buyers should keep
A physical sample is important, but it should not be the only record. Production, inspection, and reorders need a written trail that explains what was approved.
- Sample request and objective for each round.
- Measured comment sheet with revision status.
- Approved material and color standards.
- Size-set measurements and grading notes.
- Signed golden sample and sealed duplicate or detailed photo record.
How to brief the factory
Tell the factory what the current round must prove and which temporary substitutions are acceptable.
- Sample type and required quantity.
- Base size, wearer profile, and fitting protocol.
- Mandatory production materials versus acceptable stand-ins.
- Logo strike-offs, color standards, and packaging mock-up needs.
- Deadline for comments and target bulk release.
Attach the available files to the RFQ. If information is missing, ask the factory to list assumptions in the quotation so those assumptions do not become surprise charges later.
Buyer checklist before moving forward
A sample round is complete when comments are closed, not when a parcel arrives.
- Every comment is accepted, rejected, or assigned to the next round.
- Fit and measurement changes are reflected in the tech pack.
- Material substitutions are visible in the sample record.
- The pre-production sample uses production-intent processes.
- Golden-sample duplicates are available for production and inspection.
Give every sample one purpose, one comment owner, and one written approval decision.
Key takeaways
- Name samples by the question they answer.
- Separate fit approval from final material approval when necessary.
- Use measured consolidated comments.
- Check graded sizes before bulk.
- Sign a production-intent golden sample and retain references.
