20 Years of Sustainable Sock Expertise

Every product we produce embodies our firm commitment to a more sustainable future.

WHO WE ARE

Shanghai Aidai Industrial Co., Ltd.

FOCS has been dedicated to the production of eco-friendly and sustainable socks for over 20 years. Since our founding, we have focused exclusively on organic, recycled, and responsibly sourced materials — building deep expertise in certified sustainable hosiery manufacturing.
We primarily serve clients in Northern Europe, Western Europe, North America, and Oceania — markets where sustainability is not just a trend but a core value. Our partners trust FOCS to deliver products that meet the highest environmental and social standards, backed by internationally recognized certifications including GOTS, RWS, GRS, OEKO-TEX 100, Higg Index, BSCI, BCI, ISO 14001, and FSC.
From GOTS organic cotton socks to GOTS organic linen clothing, from RWS wool socks to GRS recycled swimwear, every product we make carries our commitment to a more sustainable future.

What Drives Us Forward

Sustainability is not a marketing label for us — it's the foundation of everything we do.

Organic First

We prioritize certified organic materials — GOTS cotton, GOTS wool, organic linen — grown without harmful chemicals, protecting both people and planet.

Circular Economy

We champion recycled fibers through GRS certification — turning waste into premium products, from recycled cotton socks to fishing net swimwear.

Ethical Production

BSCI compliance ensures fair wages, safe working conditions, and social responsibility throughout our supply chain — from farm to factory.

Environmental Care

ISO 14001 and Higg Index certified — we continuously measure, reduce, and offset our environmental impact across all operations.

Full Traceability

Every product is fully traceable — from certified raw material origin to finished delivery — giving our clients complete supply chain transparency.

Partnership Approach

We work as an extension of our clients' teams — offering OEM/ODM support, design assistance, and flexible production to bring sustainable visions to life.
