Sealskinz sock sizing
Sealskinz prints 1 chart for the models here: adult (UK/global site). The Sealskinz size chart page shows each one as the maker prints it, with the models that use it.
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.
Look up your size. 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.
Ordinary returns require new, unwashed and unworn goods with original packaging and tags. Use the return portal for the country and website on your order; faulty goods follow the separate claim process.
