Terrain Walking 2.0 – Dual Merino
Merino wool inner and outer
Dual merino warmth. Waterproof protection – Refined.
Terrain Walking 2.0 represents a major step forward in waterproof sock design. Built with dual merino wool layers on both the inside and outside, it delivers noticeably improved warmth and comfort compared to traditional single-merino waterproof socks. By surrounding the waterproof membrane with natural merino wool, Terrain Walking 2.0 retains heat more effectively while preserving the soft, premium feel of a high-quality merino walking sock.
Designed for everyday walking in cold, wet conditions, it keeps your feet dry, warm, and comfortable – without the synthetic shell feel common in waterproof socks.

Dual Merino Construction — Enhanced Thermal Performance
Unlike standard waterproof socks that rely on a single merino inner layer paired with a synthetic outer, Terrain Walking 2.0 uses merino wool on both sides of the waterproof membrane.
This dual-layer approach significantly improves thermal performance by:
• Creating two natural insulating zones that help retain body heat
• Reducing heat loss through the outer layer in cold, wet environments
• Allowing the waterproof membrane to function within a more stable thermal range
The result is greater warmth than single-merino waterproof socks, achieved through smarter material placement rather than added bulk.
Frequently Asked Questions
Q: Why do I need waterproof socks if I already have waterproof boots?
A: Boots can be heavy and slow to dry. Once water gets in from the top, your feet stay wet. Waterproof socks offer a lighter, more flexible solution for stream crossings or mixed-weather days.
Q: Are waterproof socks fully rain-proof?
A: Not entirely. They repel rain and mud, but extended exposure can allow water to enter from the top. Use with gaiters or waterproof trousers for maximum coverage.
Q: How breathable are they?
A: Our waterproof socks use a British-made Porelle membrane with 70% breathability, letting sweat escape while keeping water out.
Q: Why is it better to choose a size up?
A: The laminated waterproof construction has less stretch than ordinary socks. Size up if you have wide feet or are between sizes for a better fit.
Q: How should I wash them?
A: Machine wash cold with mild detergent and air-dry inside out. Avoid direct heat or high tumble settings to protect the membrane.
