Smartwool sock sizing
Smartwool prints 2 charts for the models here: unisex, kids’. The Smartwool size chart page shows each one as the maker prints it, with the models that use it.
unisex: Use the range for your model. Smartwool gives no rule for between sizes: try both sizes with your boots and check heel position and toe room.
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 Smartwool socks
Smartwool’s hiking socks in this guide allow gentle washing in warm or cool water and low tumble 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 two-year satisfaction guarantee covers direct and authorized-seller purchases, with resale exclusions. Approved US claims receive a digital gift card; retain proof of purchase and the pair in case requested.
If you buy direct from the brand, you can return unused, unwashed and unaltered items within 30 days. There are no exchanges; return an eligible pair and order the replacement size separately.
