SmartWool PhD Ski Mid Sock - Women's

Wool-On-Wool technology adds a second layer of wool to the Smartwool Womens PhD Ski Mid Sock, so its even better at holding heat, not to mention more sustainable as well. This over-the-calf sock has Smartwools 4-Degree Banded Fit system and Strategic Mesh Zones, for perfectly smooth in-boot feel and efficient moisture management. The padded impact zones protect your shin, toes, and heel, and the mid-weight thickness makes the PhD Ski Mid ideal for very cold days in lower-volume boots.
