Whether you're traveling or embarking on a fun day hike, the Smartwool Women's PhD Outdoor Light Pattern Mid Crew Socks are designed to keep your feet and toes feeling comfortable and fresh. Merino wool fabric manages moisture and temperature, and it's odor-resistant in case you're far from a washing machine for days at a time. Smartwool's 4 Degree Elite fit system uses two elastics for greater stretch and recovery to keep the sock from shifting or bunching in your shoe, and subtle cushioning in high-impact areas enhances comfort and durability. Strategically-placed ventilation zones promote refreshing airflow, and the virtually seamless design eliminates painful pressure points and irritating chafing.
