CEP sock sizing
CEP prints 2 charts for the models here: unisex, calf size. The CEP size chart page shows each one as the maker prints it, with the models that use it.
unisex, calf size: CEP sizes its low and mid socks by shoe size and its tall socks by calf circumference. If your calf falls between two sizes, CEP says to take the larger one.
Look up your size. See the fit checklist for heel position, toe room and cuff clearance.
Wash and dry CEP socks
CEP’s hiking-sock pages say: gentle machine wash cold (up to 30°C / 86°F), no tumble drying, no bleach, no iron, no dry cleaning. Its general care page allows tumble drying on low, so the label on your pair decides.
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
CEP guarantees the compression of its socks for 6 months from purchase: if a pair loses its squeeze in that time, contact CEP and it arranges a replacement after checking it. Snags, runs and holes are not covered, and pairs bought from a shop go back through that shop.
Start a return within 30 days of purchase for a full refund, or within 90 days for an exchange or store credit, in the original packaging; wash any pair you tried on first. A refund to your card costs a $6.95 return label fee, unless you added Return Care ($1.95) at checkout; an exchange or store credit costs nothing. Some closeout items are final sale.
