Editorial take
Sealskinz has built its reputation on keeping feet dry, and their Waterproof Cold Weather Mid Length Sock largely delivers on that promise. This isn't a sock for every occasion, but when you absolutely need waterproofness, it's a reliable choice. The three-layer construction, featuring a hydrophilic membrane sandwiched between a Merino wool blend interior and a durable nylon exterior, is key to its performance. The Merino lining provides warmth and wicks moisture away from the skin, which is crucial for comfort in cold, wet conditions, while the outer layer handles abrasion and the brunt of the elements. It effectively blocks water from penetrating, making it invaluable for stream crossings, wet trail segments, or unexpected downpours where waterproof boots might not suffice or are impractical.
From a performance standpoint, the sock does feel thicker than standard hiking socks due to its layered build. This can impact footwear fit, so consider sizing up your boots or shoes if you're frequently wearing these. While breathable for a waterproof sock, it's not on par with non-waterproof options, and you'll notice some clamminess during sustained high-exertion activities. Its mid-length cut offers good coverage for most hiking boots, preventing water from splashing in over the top. Durability holds up well to regular use, though like any waterproof membrane, consistent friction or punctures can compromise its integrity over time. It's not the lightest or most packable sock, but the trade-off is its primary function.
Compared to other waterproof socks on the market, Sealskinz generally holds its own. Its mid-range price point often reflects the quality of materials and consistent membrane performance. This sock is a niche item; it's not designed to be your everyday hiking sock. Instead, it serves as a critical piece of gear for specific conditions where maintaining dry feet is paramount to comfort and safety, particularly in cold, slushy, or consistently wet environments. It's an investment for those precise moments rather than a general-purpose solution.
