Merino Wool Thermal Socks - Cushioned Winter Walking Socks

The Terrabound Merino Wool Thermal Socks are cushioned walking socks knitted from a 53.9 per cent wool blend, and that figure comes from a third party lab report rather than from a label. More than half the blend being wool is what makes them the warmest socks we sell, and it is also why one pair resists odour well enough to do three days on the hill.

The blend is 53.9 per cent wool, 25.5 per cent acrylic and 20.6 per cent nylon, which puts enough wool in for warmth and odour resistance, and enough synthetic in to survive the abrasion a boot inflicts on a sock. A terry loop pile runs across the footbed and the toe, an elasticated band holds the arch, and the toe is closed with a flat seam that lies flat against your toes.

Wool is also why these keep working when the weather turns. The fibre traps air in its own crimp, so it insulates by itself, and it carries on doing it when damp. That is the point at which a cotton or synthetic sock goes cold against the skin. The terry pile adds a second layer of trapped air underfoot. For a frosty morning walk, an hour standing still at a touchline, or a winter hill day, this is the pair to reach for.

From a Sunday hill walk to a week on a coast path, these are socks that stay where you put them and stop being something you think about.

Key Features:

• A third party lab report puts the wool content at 53.9 per cent, so you can check the figure rather than trust the label.
• Wool traps air in its own crimp and keeps insulating when damp, at the point where a cotton or synthetic sock goes cold against the skin.
• Wool at over half the blend resists odour across consecutive days of wear, which is what lets one pair cover a multi day walk.
• Acrylic and nylon make up the rest of the blend and take the abrasion that wears a pure wool sock out inside a boot.
• A terry loop pile across the footbed and toe traps a second layer of air underfoot and absorbs the impact of a long descent.
• An elasticated band across the arch stops the sock creeping down inside your boot on the walk in.
• The ribbed cuff holds the sock at the calf without leaving a tight band around your leg.
• Crew height sits above the collar of a walking boot, so the leather rubs the sock rather than your ankle.
• Buy two or three pairs together and the price per pair drops, so a spare for the rucksack costs less than buying one pair on its own.

Terrabound builds practical outdoor kit for people who are out every week, whatever the forecast. The Merino Wool Thermal Socks come in nine colours, from coffee and grey through navy, blue and sage green.

Pair them with our Women's Walking Boots or Men's Trail Shoes for a setup that works from the ground up.
