At Teko we are not only committed to making the best socks ON the planet - we strive to make the best socks FOR the planet too! We approach sustainability as a balancing act. It's not possible to produce a product without using energy and natural resources, so it's our job to minimize our footprint at every stage. A major element of our commitment is constant research of new materials and production techniques to make that footprint smaller. Our organic merino wool comes from Argentina from a group of farms that have been raising sheep organically for decades. Only non-motorized methods are used to herd the sheep. They are fed only organically-grown food and are not subjected to hormones, vaccinations, mulesing, or chemical drenches. Their grazing area is never sprayed with pesticides, herbicides or fertilizers. Strict water conservation methods are employed, as are protections against overgrazing. Organic merino wool is substantially more expensive than the non-organic alternative, but Teko believes the investment is worth it, both for consumers and the planet.
