The Pearl Izumi Elite Wool Women's Socks provide a supportive fit and excellent thermo regulation for any season, ranging from hot summer days to crisp fall mornings. The key to their year round versatility is Elite Transfer Merino wool fabric, with strategically placed merino along the toe and heel for improved comfort without added bulk. Merino enhances comfort by actively wicking sweat to promote a dry, comfortable feel. Mesh ventilation at the top prevents your feet from overheating and soaking in perspiration. Other key features include an ultra smooth toe box, as well as anatomic arch compression for an exact fit.
