Not many things boost morale on the trail like dry feet free of blisters and frostbite. It is also a goal that is sometimes difficult to achieve. Sealskinz waterproof socks are a very good tool for the job and make life easier in difficult conditions.

Three questions arise when something is advertised as waterproof and breathable. The first two are both "is it, though?" (making that squinting Thor face) and the third is a matter of durability.

We have used Sealskinz socks extensively and they are actually 100% waterproof and very breathable - more so than many boots with a waterproof membrane! The hydrostatic head is >20,000 mm and breathability is also at a very good level, we suspect this is in part because the membrane is so close to the skin that it remains warm - all membranes work better in the warm because it reduces condensation.

The sock features a three-layer bonded construction that combines a hydrophilic membrane between a Merino wool interior for warmth and sweat-wicking, and a durable Nylon blend exterior with 4-way stretch for great fit and wearability. The construction omits many seams and the toe boxes are hand-linked to keep everything nice and flat. The elastic supports at the ankles, heels, and insteps improve the fit.
