About

Where do socks go when they disappear? Probably one of the greatest mysteries. We, at Third Sock Co., looked for a solution instead of the answer.

Third Sock Co. is the American premium colourful socks brand that aims to reinvent the pair, offering 3 socks in a pack, in case one goes missing.

Founded in 2025, Third Sock Co. reflects the passion for colourful socks, matching or standing out from the outfit and was born from the disappointment of missing socks.

PRODUCTION & DESIGN

We produce our Third Sock Co. socks in the EU with good care and responsibility, respecting the regulations of labour and quality standards. All the packaging is made of recycled cardboard.

As the sister brand of Soseta3, established in Europe in 2014, it brings a decade of creativity, innovation, and missing-sock solutions to the US.
