Swiftwick Pursuit Zero

The 2016 Swiftwick Pursuit Zero is a compression sock. The lightest and shortest instance of the Pursuit, the Zero fits snugly within the confines of a road shoe, providing comfort across the board. Made of nylon and Merino wool, it's smooth on the skin, raising no blisters, with reinforcements worked in to support arches and keep the fabric from bunching at the toe. Offered in several sizes and a number of low-key colors.
A good wool-based compression sock.
