Large areas of sculpted open mesh structure promote moisture transportation away from the foot. Merino Performance Fusion Technology provides resilient padding, exceptional moisture wicking and outstanding durability for all day comfort. The Performance Fit is close and supportive that won’t slip down or bunch in your footwear. The Flat Toe Seam minimizes bulk in the toe box and the sock is kept securely in place with an engineered Women’s Specific Fit, Elasticated Arch and 3D-shaped heel cup. Built on a structure of Lycra® and set by our Thermo Fit process ensures the sock returns to its original shape and size after every wash.
