We blended soft, moisture-wicking Merino Wool with polyester and spandex, two supportive yarns that help create the perfect fit.

Merino Wool is a natural fiber that's incredibly soft, moisture-wicking, and will keep you warm in the winter and breezy-cool in the summer. We also took this super yarn and blended it with a little bit of polyester and spandex to help perfect the fit of every pair, and create the built-in arch support so many feet now know and love.
