Shoe Size Converter
Convert EU, US, UK and CM — with brand-specific notes for rep buyers.
How should rep buyers convert shoe sizes?
Rep buyers should use centimeter or insole length as the final shoe-size reference whenever a seller provides it. EU, US, UK, and women's conversions are useful for quick filtering, but Weidian, Taobao, and 1688 batches may follow factory lasts rather than retail sizing. Measure a comfortable pair from heel to toe, compare that number with the seller's chart, then account for brand-specific fit notes before selecting a Litbuy variant. Sizing risk is higher for designer sneakers, narrow lasts, boots, women's-to-men's conversions, and batches with mixed community reports. Ask for extra QC measurement photos when the pair is expensive, the chart is unclear, or the batch runs large or small. Confirm both shoe labels before shipment.

Brand-Specific Sizing Notes
Rep sizing on buying agents often differs from retail expectations. Key notes:
Run 1 full size large — order EU 43 if you wear US 10
Runs large — go 1 size down from your regular size
Runs true to size — order your standard US size
Generally true to size across most rep batches
Half size up for narrow feet, TTS for wide feet
True to size — most batches consistent with retail sizing
True to size — order your normal size
Runs slightly large — consider half size down
Runs small — go at least half size up
How to Use Shoe Sizes for Rep Orders
Use centimeters as the final reference whenever a Weidian, Taobao or 1688 seller provides an insole length. EU, US and UK conversions are useful for quick comparison, but rep batches can follow factory-specific lasts rather than retail sizing. If your best-fitting shoe has a removable insole, measure heel to toe and compare that number with the seller chart before selecting a size in Litbuy.
Sizing risk is highest for designer footwear, oversized silhouettes, narrow lasts, women's-to-men's conversions, and batches with community reports of being large or small. When QC photos arrive, ask for outsole or insole measurement photos if the size is expensive to return or if the seller chart is unclear.
Before You Ship
- Compare CM length, not only US or EU labels.
- Check both left and right shoe labels in QC photos.
- Account for thick socks or insoles on boots and runners.
- Ask for extra measurement photos before approving high-value pairs.
