In October 2009, Merrell launched a new line of socks based on their EWE (Enhanced Wool Endurance) technology. The EWE marries each strand of wool fiber with a strand of Duraline Synthetic fiber. This technology combines the natural warmth of wool, with the durability and wicking properties of a synthetic fiber. I've been testing the sock for the last two months, and I've been please with the results.
