The Smartwool PhD Nordic Light Sock is a highly technical sock designed specifically for cross-country skiers. Smartwool internal lining to manage moisture, temperature and odor; strategic mesh zones for maximum ventilation, and Duroyarn reinforcement for added comfort and durability. WOW technology puts wool in high density impact zones to reduce abrasion and shock, 4-Degree Fit System creates bands around the ankle, arch and instep for performance fit that lasts all day. Smartwool did pressure sensors to test athletes' feet in a variety of conditions to map out pressure zones and used this data to fine-tune cushioning and ventilation areas to optimize fit, comfort, blister prevention and durability. BNS skiers have used these socks extensively and are among our favorites for the high-quality, fit and durability.
