Our lightest, thinnest sock minimizes friction on hikes and mountain runs.Built to hug the foot, our lightest sock minimizes cushioning and aligns with the fit of our shoes to create a system that helps mitigate friction on long mountain runs and hikes. Made with wicking fibres, the performance polyester yarns help manage temperature and moisture. The minimalist design eliminates the toe seam, has a gridded construction at the arch for support and airflow, and a collar height that helps seal out trail debris.
