Frequently Asked Questions
Do Chinese factories use EU sizing?
Most export-oriented factories label in EU sizes but can produce to US/UK specs with provided size charts.
How much size variation is normal between batches?
±0.5 EU size between production batches is acceptable; beyond that requires last adjustment or QC hold.
Should I include CM measurements on my size chart?
Yes. Centimeter foot length is the most objective cross-market reference and reduces confusion for global e-commerce listings.
Do athletic and leather shoes fit the same size?
Not always. Athletic shoes often fit roomier; leather dress shoes may feel narrower on the same last. Test each category separately.
How do I specify size run on a purchase order?
List each size and quantity explicitly, e.g., EU 40×20, 41×30, 42×30, 43×15, 44×5. Avoid vague terms like "assorted."
What if my retail market uses US sizes only?
Provide the factory a US-to-EU conversion chart approved on the golden sample. Labels should match your primary sales market.
Can half sizes be produced at the same MOQ?
Usually yes, but each half size counts toward total MOQ. Some factories require full-size-only runs for first orders under 100 pairs.
