Sealskinz socks by what you need

Sealskinz sock sizing

The lookup includes the adult (UK/global site) chart. Match the chart to the exact model, then check the heel and toe fit in your footwear.

Adult (UK/global site): Sealskinz prints this chart on its UK/global product pages, with US, EU and UK sizes. Check that your store sells the same construction; Hydrostop cuffs need their own comfort check.

Open the brand size lookup. See the fit checklist for heel position, toe room and cuff clearance.

Wash and dry Sealskinz socks

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.

A different instruction on the exact sock takes precedence over general brand guidance. Use the care lookup and your own drying estimate in the rotation planner.

Guarantee and return checks

The lifetime manufacturing-fault guarantee applies to products made from summer 2020 onward and bought direct or from verified stockists. Wear, misuse and accidental damage are excluded. Retailer purchases qualify for replacement rather than a direct-store refund.

Sealskinz.com orders delivered in the UK can be returned or exchanged free through the Royal Mail returns portal, within 30 working days of delivery. Socks must be unworn, in their original packaging with the tags on (faulty goods excepted). Socks bought in a shop go back to that shop.

Separate the guarantee from store returns.
