Darn Tough sock sizing
Darn Tough prints 4 charts for the models here: men’s and unisex, women’s, women’s, kids’. The Darn Tough size chart page shows each one as the maker prints it, with the models that use it.
men’s and unisex, women’s: Darn Tough advises sizing up between sizes. Chart coverage does not mean every model is sold in every listed size.
women’s: Darn Tough advises sizing up between sizes. Women’s XL is offered only in selected styles; a chart match does not establish model availability.
kids’: Kids’ US and UK sizes run from toddler sizes into youth sizes, so this lookup reads the EU column; the whole table is shown as printed.
Look up your size. See the fit checklist for heel position, toe room and cuff clearance.
Wash and dry Darn Tough socks
Wash inside out on a cold, gentle cycle. Use low tumble heat or hang dry. Avoid bleach and dry cleaning.
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 guarantee offers replacement when a pair no longer meets your expectations. Keep both socks for the claim; a receipt is not required. Use the claim process for your country.
Direct US orders have a 90-day return or exchange window, including worn or washed pairs. Start with the direct-store return process for a recent order, and the guarantee process for an older pair.
