There are two kinds of sock factories in the world: those built for bulk, and those built for flexibility. Most are built for bulk. That is not a bad thing. Big factories can produce huge volumes at low cost. But they are not always the right fit for a new brand.
A bulk socks factory usually wants orders of 1,000 pairs or more. If you need 50 pairs of custom logo socks, they may not even reply.
Small batch partners are different. They are set to handle customized socks with a minimum order quantity. They can customize socks for small brand wholesale, personalized wholesale socks, and customized socks for teams. They may not be the cheapest pair, but they give you room to grow.
At SOXFUN, we are a small batch partner. When customers expand their scale, we also have large sock production workshops. The best approach is usually to start small, prove the design, and then go big.
You don't have to always choose one. You just need to choose a suitable one for today.
