When you are considering a membrane sock

The Runton combines three layers, an Aquasealz membrane and a merino-blend inner sock.

Keep in mind: Water can still enter over the cuff. Plan for cuff coverage and a spare dry pair; a membrane is not a substitute for either.

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

The Runton UK product page allows washing at 40°C / 105°F and low tumble drying or drip drying. Do not bleach, iron or dry clean.

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.
