This guide is written for overseas retailers, marketplace sellers, outdoor brands, gift companies, and sourcing teams that want better sock leads before they start a factory conversation.
Use foot length and shoe size together
International customers search by US, UK, EU, and sometimes foot length in centimeters. A conversion chart reduces returns and improves confidence, especially for gift sets and kids products.
Separate adults, kids, and compression products
Performance and compression socks may depend on calf circumference and pressure level. Kids socks often need age guidance, but foot length is more reliable for fit.
Add sizing content to category pages
Sizing copy can rank for practical search terms and help leads feel the site is trustworthy. Include height definitions like no-show, ankle, quarter, crew, boot, knee-high, and over-the-calf.
Questions to include in your RFQ

- Can the supplier provide private label packaging, barcode labels, and carton marks?
- Which tests are available for shrinkage, colorfastness, pilling, and abrasion?
- How long do sampling, pre-production approval, and bulk production usually take?
