TEKO eco RUN 1.0 Ultra Triaxial Merino Wool Socks - Low Cut Ultralight (2026 edition)

Master your pace with the TEKO Ultra 1.0 Triaxial—the ultimate fusion of natural performance and technical precision. Engineered in Italy, these socks utilise our proprietary Merino-Synergy™ technology to provide a high-speed "Responsible Interface" for the serious distance runner. By blending the finest Mulesing-free Merino wool with high-tenacity recycled fibres, we’ve created an ultralight, super-breathable shield that excels from the Lake District trails to urban marathons.

The Ultra 1.0 is purpose-built for the UK’s most demanding racing conditions. Our proprietary Triaxial Fit System provides a secure, three-point anatomical wrap that moves in total harmony with your foot, whilst the seamless toe construction creates an invisible, second-skin barrier against friction. This zero-cushioning model offers maximum "ground-feel" and airflow, making it the definitive choice for those who demand elite performance with a lighter environmental footprint. Backed by the TEKO Lifetime Guarantee, it is the only technical running sock to fuse elite Merino thermoregulation with a non-slip Triaxial fit.
