Worstead Waterproof Cold Weather Knee Length Sock - Warm, Dry Feet

Our review of the Worstead Waterproof Cold Weather Knee Length Sock finds it best suited to people who spend long hours outdoors in cold, wet conditions and need dependable warmth plus protection. The single biggest reason to buy is its combination of a hydrophilic AQUASEALZ membrane and merino-blend outer layers, which aim to keep feet warm while blocking external moisture. Worn by military personnel and crafted in Norfolk, this knee-length sock targets winter hikers, skiers and anglers who value durability and a snug, over-calf fit.

Key Features

• Waterproof membrane: The AQUASEALZ hydrophilic membrane prevents external water entry while expelling internal moisture to help keep feet drier during extended cold-weather use.
• Merino blend construction: A merino wool mix provides natural warmth and breathability so the sock remains comfortable even during active use.
• Knee-length coverage: The taller profile adds protection for lower legs and improves the seal inside boots to reduce water ingress around the cuff.
• Durable build: Handcrafted at the Sealskinz factory in Norfolk with rugged materials designed to withstand demanding environments and prolonged use.
• Easy care: Machine wash at 40oC and tumble dry low or drip dry to preserve the membrane and fabric without special maintenance.

Who It's For

The Worstead sock is ideal for winter hikers, skiers, kayak anglers and anyone using motocross or heavy-duty boots who needs extra waterproofing and insulation. Its knee-length design and durable construction suit users who spend long periods outdoors and require a robust, breathable sock that handles wet, cold conditions.

Those who want ultralight layering for high-output aerobic activities or a thin liner for everyday indoor use should look elsewhere, as this sock prioritizes warmth and waterproofing over minimal bulk. Also, shoppers seeking a guaranteed, failproof membrane in all conditions should note that some users report mixed waterproof results in extreme or prolonged submersion.

Pros & Cons
