Keen launches work socks.

Keen aims to redefine durability with a new line of heavy duty socks built to withstand the wear and tear of steel toe cap boots. Guaranteed for life and made in the U.S.A. from moisture-wicking merino wool, the socks feature Dura-Zone high-tenacity nylon fibers, which are 15 times stronger than steel, in the heel and toe, and impact cushioning in key areas offers comfort and protection. Left and right designs and a heel hold cup construction provides a secure fit, while Keen’s Wunderseam seamless toe in the flex zone helps avoid chaffing. The socks will available in men’s sizes M, L and XL come Fall ’14.
