KAJA · Sourcing Guide
A shoe sole sample is a reference for discussing the component your footwear project needs. Reviewing only its overall appearance can leave important details unresolved. A more useful review compares the sample with the requested model, construction, finish, colors and sizes, then checks how it works with the intended upper and last.
The checklist below is intended to help footwear manufacturers organize a sample review with KAJA. It does not replace the project’s own testing or production approval procedures.
Identify Exactly Which Sample You Are Reviewing
Record the model number and the requested options. For a style with several finishes, include the construction or finish name and its reference code. Label separate samples clearly when comparing colors or construction options.
Keep the relevant quotation, drawings and reference images alongside the sample. If the sample was prepared to demonstrate only part of the proposed specification, record what remains to be confirmed.
Compare the Appearance with the Agreed References
Review the sole profile, tread, visible surfaces and painted areas against the model and finish requested. Compare the intended color areas with the references supplied for the project.
On KAJA product pages, the color-count option describes the number of colors, not the color names. A two-color selection still needs a clear agreement about the actual colors and their placement. Mark questions on photographs so the factory can identify the area being discussed.
Check the Size List and Tooling Scope
Confirm which size the sample represents and which existing mold sizes are included in the proposed order. Developed sizes vary by model. Additional sizes may require tooling review, even if they fall within a general size development range.
If the order includes sizes that have not yet been confirmed, keep them on the review list. Do not treat approval of one sample size as confirmation of tooling for every size in the collection.
Review Compatibility with the Upper and Last
The sole is a component of the finished footwear. Review it with the intended upper and last rather than evaluating it as a separate object only. Share the relevant construction information and discuss any fit or interface questions before approving production specifications.
If your team needs a production trial or a particular validation process, agree the review requirements with the supplier. Keep a record of any changes requested after the trial.
Confirm Material and Performance Requirements
Make sure the proposed material construction and any required specifications are part of the discussion. If hardness, appearance or other properties matter to the project, state the agreed requirements instead of relying on a general material name.
Customers arrange testing. KAJA works with the feedback to adjust formulations toward agreed performance targets. Sample appearance alone is not evidence of a particular test result, certification or suitability for every intended application.
Record Approval and Open Questions Separately
Keep a clear list of what has been approved and what is still pending. This can include color references, painted areas, logo details, size availability, tooling changes or testing feedback.
Confirm the final specification, quantities and production schedule with the supplier after sample review. MOQ and the schedule depend on the material, construction, colors, sizes and tooling requirements of the project.
Requesting Samples from KAJA
Free samples of existing sole styles are available, with shipping paid by the customer. New development, mold costs and sampling arrangements for undeveloped designs are agreed separately.
