When the temperature drops but your running routine doesn't, the Smartwool Run Cold Weather Targeted Cushion Crew Socks are engineered to keep your feet comfortable and protected through every winter mile. The merino wool blend naturally regulates temperature while fighting odor, ensuring your feet stay warm without overheating during intense cold weather runs. Strategic mesh ventilation zones work alongside the wool's natural breathability to manage moisture, while targeted cushioning in the heel and forefoot delivers impact protection exactly where runners need it most. Built with a narrower profile specifically designed for women with narrower feet, these crew socks feature Smartwool's 4-degree elite fit system that uses dual elastic technology to keep the sock securely in place, eliminating bunching and hot spots that can derail your winter training sessions.
