Arctix Sport Extreme Merino Wool Socks Thermal Fishing Socks 35-46

Arctix Sport Extreme are very warm Merino wool socks designed to keep your feet comfortable during long, cold sessions on the bank. Whether you are standing in a river, sitting behind a pod on a frosty morning or walking miles along a windswept reservoir, these socks are built to retain heat while managing moisture, making them a practical choice for anglers who refuse to let cold feet cut a session short.

The secret lies in the Merino wool content. Merino is naturally breathable, and its fine fibre structure creates a layer of trapped air between the sock and the skin. This insulating layer holds warmth close to your feet while allowing excess moisture to escape, so your feet stay dry rather than clammy. Unlike basic cotton socks that flatten and chill when damp, Merino wool continues to insulate even when conditions turn wet.

Merino wool is also naturally antibacterial, which helps prevent the build-up of odour during multi-day trips or when you are wearing the same boots from dawn until dusk. This makes the Sport Extreme a sensible choice for fishing holidays, bivvy sessions and any situation where fresh socks are not an option.

The top section of the sock is designed to grip the leg snugly, keeping the sock in place so it does not slide down inside your wellies or wading boots. This secure fit reduces bunching and rubbing, which is particularly welcome when you are wearing the socks inside tight-fitting neoprene or rubber footwear.

The blend of materials has been carefully balanced for performance. 40% Merino wool provides the warmth and breathability, 40% acrylic adds durability and shape retention, 12% nylon reinforces the heel and toe areas, 5% cotton adds softness against the skin, and 3% elastane gives the sock its stretch and recovery. The result is a sock that holds its shape wash after wash while remaining comfortable for hours on end.

Available in three size ranges, the Arctix Sport Extreme suits a wide range of foot sizes and is equally at home in fishing wellies, wading boots, walking boots or everyday footwear during the colder months.
