Engineered to be long-lasting, DeFeet products are sustainably manufactured within a local supply chain. Our wool goods are made from USA-grown Merino, traveling from Oregon to the Carolinas for processing and knitting. Our Repreve® recycled poly is manufactured right here in North Carolina from locally collected post-consumer water bottles. DeFeet socks come with a 5-year warranty. If you are not satisfied with your product, we will replace it.

Woolie Boolie socks with the RWS logo are 70% RWS-certified by CU 885920. The Responsible Wool Standard (RWS) is a set of audited protocols establishing high levels of sheep and land management practices, promoting healthy ecosystems, biodiversity, and animal and worker welfare.

100% of the wool in RWS-certified socks has complete traceability through each step of the supply chain from the ranches and sheep where it grows to the retailers where it is sold.

Our RWS-certified products use wool grown by the Shaniko Wool Company and RWS-certified family-owned ranches in the Western United States.
