Icebreaker sock sizing
Icebreaker prints 3 charts for the models here: men’s, women’s, kids’. The Icebreaker size chart page shows each one as the maker prints it, with the models that use it.
men’s: Use the men’s chart shown on this exact product page. Icebreaker prints no women’s sizes in that chart; use the men’s column.
women’s: Use the chart printed for the exact model and audience. Where a system is not printed, this lookup does not convert from another one.
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 Icebreaker socks
Icebreaker’s hiking socks in this guide: machine wash cold on a gentle cycle and dry flat. 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 current US warranty covers faulty fabric, stitching or manufacturing for one year with authorized-seller proof of purchase. It is not a lifetime wear guarantee. The separate comfort guarantee is 30 days; retailer purchases begin with that retailer.
Direct online returns require an unworn, unwashed item in original packaging; final-sale and pro orders are excluded. The page says 30 days and uses both purchase and ship date wording, so begin within 30 days of purchase. Exchanges require a refund and new order.
