What are the warmest socks for winter?
The warmest winter socks combine insulation, moisture management, and protection against wind and water, and Sealskinz designs tick all those boxes. Our thermal socks often include a layer of merino wool or wool blends to trap heat and cushion the foot, backed by insulating synthetics that maintain loft when damp. We pair that with our Aquasealz™ membrane to block external chill while letting moisture from inside escape. When everything works together: insulation, moisture control, and weather barrier, your feet stay warmer in harsh winter conditions.
How do thermal socks prevent cold feet?
Thermal socks prevent cold feet by combining insulation and moisture control. The insulating fibres (like merino wool) trap a layer of warm air close to the skin, acting as a buffer against ambient cold. At the same time, by wicking sweat away and allowing it to pass through membranes or breathable layers, they minimise internal dampness, which would otherwise cool by evaporation and cause chill. Sealskinz socks are built with linings that draw moisture from your skin into middle layers, and then push it outwards through a breathable outer shell. In waterproof models, a bonded membrane keeps external water out while still permitting this moisture transfer. In this way, feet remain dry, warm, and comfortable.
Can thermal socks be worn for hiking or running?
Yes, thermal socks are absolutely suitable for hiking and running, especially in cooler conditions. The key is choosing a design that offers warmth without overheating or moisture buildup during activity. Sealskinz cold weather and extreme cold weather socks are built to perform in motion: our waterproof variants add protection from wet terrain, puddles, or snow while maintaining comfort on the move. Whether you're hiking mountain trails in winter or doing brisk cold-weather runs, the right Sealskinz thermal socks can offer the insulation and protection you need without sacrificing performance.
