Size Guide
Merino has stretch, but fit matters — a sock that slides is a sock that blisters.

How to measure your foot
Stand on a sheet of paper with your heel against a wall. Mark the tip of your longest toe, then measure from the wall to the mark in centimetres. Measure both feet late in the day and use the larger number.
Between two sizes?
Size down for a closer, no-slip fit in trail and running shoes. Size up if you have a high instep or wear thick winter boots. All three models — ROCKY, LOGAN and COAST — use the same size scale.
Care so the fit lasts
Cold machine wash, gentle cycle, inside out. No bleach, no fabric softener, no tumble dry. Lay flat to dry and the built-in shape memory does the rest.
