Smartwool Running SocksSmartwool Running Socks

Runners are notoriously fussy about fit and performance. SmartWool Running Socks has them covered with their new Performance Running Socks Series---eight new running-specific styles, two of which are made specifically for women. Runners can choose between a variety of weights: light cushion, medium and non-cushion in three heights: micro socks, mini-crew socks or 3/4 crew socks. SmartWool running socks outperform every synthetic textile in the critical task of moving moisture away from the body, which means that SmartWool running socks keep a runner's feet cooler and drier. SmartWool also prevents odor problems that plague synthetic running socks. SmartWool running socks stay in place on the foot and avoid bunching with the exclusive, anatomically deigned "Smart Fit System", which includes a contoured flex zone, and elasticized ankle and arch braces for improved support and fit. Each weight and style in the Smartwool running socks line come in a variety of colors.
No matter what their pace or distance, even the most finicky runner will find that the SmartWool Performance Series Running Socks exceed their expectations. SmartWool is the leading performance brand of wool-based apparel, socks and accessories. Nothing can compare to SmartWool for the ultimate in performance, comfort and easy care. SmartWool is superior at vaporizing moisture, controlling temperature and odor and is guaranteed not to shrink. It's also a renewable resource that illustrates the design genius of evolution.
