About This Product


To give your feet the most comfortable possible environment, we teamed up with veteran sockmaker, Wigwam, to build a sock worthy of the llama.

The Libre Sock is made with llama blend, which starts with our breathable, moisture-wicking, naturally hypoallergenic llama fiber. To boost the material's strength and add stretch, we blended the llama fiber with nylon. In the areas where your foot is working hardest, we added durable, moisture-wicking polyester and soft terry to absorb impact.

Wrap-around mid-foot rib-knit panels provide light compression to add a bit of arch support, and no-quit cuffs eliminate slippage to all day, no matter what you're doing. For comfort, style, and all-day, every day performance, there's no better place to put your feet.


  • Proprietary llama-fiber/nylon blend
  • Polyester toe, heel, & midfoot
  • Compressive cuff & arch support
  • Cushioned terry toe & heel
  • Split-color heel
  • 7in cuff height
