Minus33 sock sizing
Minus33 prints 1 chart for the models here: unisex. The Minus33 size chart page shows each one as the maker prints it, with the models that use it.
unisex: Use the range printed for the exact model.
Look up your size. See the fit checklist for heel position, toe room and cuff clearance.
Wash and dry Minus33 socks
Turn inside out, machine wash cold with a gentle or wool detergent and tumble dry low. No bleach or fabric softener.
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
Minus33’s socks made in New Hampshire (the Mountain Heritage line) carry a five-year warranty: if a pair wears out early or shows a manufacturing defect within five years, send it back washed with the claim form for store credit worth that style. Other Minus33 socks, such as the imported Day Hiker, have a one-year defect warranty.
Return a purchase within 30 days, with the receipt, for a replacement or refund, after authorizing it on Minus33’s online form. Wash items before you send them; the return postage is yours.
