A boot sock for mountain hikers and walkers who enjoy the trails when the mercury plummets, the Explorer Merino Comfort provides all the support and warmth you need for cold-weather adventures. With thick cushioning for warmth, a soft-knit cuff for comfort and double density pads beneath your feet for all-day impact resistance. Featuring Merino Comfort Fusion Technology that creates a soft, fast-drying, unrestrictive and durable sock. Our Comfort Fit features a super stretchy ribbed cuff around your calf allowing the sock to be worn comfortably up or down. The toe box is closed with an almost invisible Flat Toe Seam minimising bulk around your toes whilst the sock is kept securely in place with an Elasticated Arch and 3D-shaped 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. This is the perfect sock for exploring hills and mountains in sub-zero temperatures.
