Merino Comfort Fusion Technology creates a soft, fast-drying, durable sock with a the super stretch ribbed cuff providing a close supportive fit on your foot with a looser unrestrictive fit around your calf, allowing the cuff to be worn up or down.… The zonal padding system provides extra support whilst the open mesh structure promotes increased moisture transportation. The Flat Toe Seam minimises 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.
