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.
