Change socks before they are soaked
Carry a second pair on long or hot days and swap at lunch. Hang the damp pair on your pack to dry. A dry sock is also a big part of avoiding blisters.
Thin socks, airy shoes
A lightweight or ultralight sock with light or no cushion holds less sweat than a full-cushion one. Mesh-topped trail shoes let more air in than leather boots. The hot-weather guide lists the thinnest socks here.
Merino or synthetic?
Merino makers often say their socks resist odor; synthetic socks usually dry with less weight of water left in them. Neither claim is measured across the socks in this guide. If odor bothers you most, try merino; if a sock that stays wet bothers you most, try a thin synthetic.
Washing and rotation
Wash socks after one or two days of wear, inside out, and let them dry completely. On a trip, rotate two walking pairs so each gets a day to dry; the trip planner shows when that works.
When to see someone
Very heavy sweating, a rash, cracked skin or an infection is a matter for a pharmacist or doctor, not a sock. This guide does not give medical advice.
