When you want a waterproof membrane for wet trails

A mid length waterproof sock with a midweight knit and an inner layer of 36% merino wool.

Keep in mind: Water can still get in over the cuff, and the three layers take more room than a standard sock, so try it in your shoes before a wet trip. Facts come from Sealskinz’s UK/global site; check the US listing matches.

Closest in Sealskinz’s range: the Surlingham Ankle Length. They differ in cuff; the weight, blend and size chart are the same.

Check the size and the shoe together

Start with the unisex chart for this exact model. Use the size lookup or the whole Sealskinz size chart to find the published range, then check the heel position, toe room and cuff in your footwear.

The maker does not give a heel-to-cuff measurement. Try the socks with your boots to see whether the cuff sits above the collar. See how sock heights differ.

Try the complete layered construction, not only one layer. Extra fabric can change toe room and pressure inside the shoe. The footwear-fit checklist explains what to check.

Care for the exact pair

Wash at 40ºC/105ºF. Low Tumble Dry or Drip Dry. Do Not Dry Clean, Iron, or Bleach.

Use the care lookup for this model’s wash and dry directions. A general wool routine should not override instructions for a membrane, a two-layer construction or a specific treatment.

Another sock to compare

Both constructions contain animal fiber (wool or alpaca). Padding: not published here, “maximum cushion” there; check each brand’s size chart.

DexShell Hytherm Pro Waterproof Mid Calf uses its own size chart. Compare the two socks to see where their height, material, cushioning and care differ. Matching specs don’t mean they will feel the same in your shoes.
