FAQ
1.How should buyers write technical specs and tolerances for Suede Slippers?
* Last and size: Write the approved last code, size chart, foot length in mm, and size tolerance, such as length ±2mm and width ±1.5mm.
* Material traceability: Lock the suede upper, lining, padding, outsole, glue, and trim by material code, supplier, and composition.
* No material change: Do not allow material substitution unless the buyer gives written approval.
* Thickness and hardness: Define suede thickness, lining GSM, padding thickness, foam density, outsole thickness, and outsole hardness.
* Color control: Use the approved physical swatch as the color standard. Do not accept visible left-right color difference.
* Batch shading: Bulk color should stay close to the approved sample, with no obvious batch-to-batch shade difference.
* Logo specs: Define logo size, placement, method, and tolerance, such as *±1mm from center.
* Packaging protection: Specify shoe stuffing, tissue paper, box strength, barcode position, hangtag, warning text, silica gel, inner carton, and outer carton.
* Inspection rules: Use ISO 2859-1 sampling and classify defects as critical, major, and minor.
2.What design parameters are often missed during suede slippers sampling?
* Vamp coverage: Ensure upper fully covers the instep.
* Forefoot room: Keep enough toe movement space, usually 5–8mm.
* Lining space: Measure the inner space after lining or sponge is compressed.
* Side-seam position: Fix the seam start point, end point, and distance from the welt.
* Footbed shape: Check the arch, heel cup, and edge curve.
* Left-right symmetry: Compare back height, vamp shape, opening, seam line, outsole, and footbed as a pair.
3.How to define durability and lifespan for Suede Slippers?
Do not promise “one-year wear” or “two-year wear.” Define durability by testable limits and use scenes.
* Flexing: Set the bending cycles, test condition, and crack limit.
* Lining wear: Define the limit for pilling, holes, flattening, or large-area shedding.
* Color fastness: Set minimum dry rub, wet rub, and perspiration ratings.
* Indoor use: Focus on lightweight construction and basic upper-sole bonding.
* Indoor / outdoor use: Add outsole abrasion, wet-floor grip, and stronger bonding tests.
* Size change: Only use this for washable styles. Set the maximum shrinkage or deformation, such as ≤2%.
* Care appearance:** For non-washable suede, define how the upper should look after professional care.
* Wear trial:** Run a 2–4 week** wear trial before bulk production.
* Final approval:Use lab reports and wear-trial results as the delivery standard.
