Woolie Boolie 6" D-Logo crew athletic cycling thick wool socks in classic solid colors with a d-logo on the side of the cuff.

The DeFeet Woolie Boolie is our cushiest sock, with a cult following for all the right reasons: woolie warmth, padded comfort, and durability.

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.
