Knit with super-fine merino wool throughout it offers superb softness next to skin while providing excellent thermal and moisture control properties. The Flat Toe Seam minimises bulk that could cause irritation and the sock is kept securely in place with an Elasticated Arch and 3D-shaped Y-heel cup. Built on a structure of Lycra®, allows our Thermo Fit process to ensure the sock returns to its original shape and size after every wash.
