Key Features of the Portwest SK34 Women's and Men's Merino Socks

  • Protective thermal socks improve comfort in cold conditions
  • Merino wool material provides maximum warmth
  • Insulating properties help prevent and manage symptoms of Raynaud's
  • Reinforced heel and toe area for added durability
  • Elasticated leg provides snug fit and unrestricted movement

Breathable Design for Maximum Comfort

For breathability, the Portwest SK34 Socks feature ventilation channels as part of their design. Merino wool also has natural moisture wicking abilities, which ensures the socks can breathe and move moisture away from your feet toward the surface of the sock. This movement allows moisture to evaporate quickly instead of keeping it near your feet, causing sweat and odours.

Comfortable Construction for All-Day Wear

The Portwest SK34 not only ensure warmth but also provide comfort. The elasticated legs of these socks provide a snug fit for the wearer, while a cushion foot sole provides extra comfort to the wearer with every step. Ventilation channels on these socks also add to their breathability for comfort all day long.

Designed for Long-Lasting Use

There's nothing worse than finding your big toes have peeped through holes in your socks, especially after only having them for a short time. To prevent this from happening the Portwest SK34 socks feature a reinforced toe area, (as well as heel area) to ensure these areas have extra durability.

What Is Merino Wool?

Merino wool is a natural fibre grown by Merino sheep. Merino wool socks, are typically the warmest type of socks. As well as their insulating properties, they are also thinner and softer than regular wool, making them easier to wear next to the skin and therefore easier to wear all day.

These types of socks are the choice for strenuous work, or work in which you're on your feet all day, as well as activities such as backpacking and marathon running. Additionally, for individuals suffering with conditions such as Raynaud's, these socks are a great way to keep discomfort at a far distance.
