Socks with hiking sandals: toe socks, thin merino or none

With strap sandals, a thin merino or synthetic crew sock adds warmth on cool mornings and keeps grit off your skin; with toe-post sandals, only a toe sock fits. On hot, wet or river days, most people go without and let feet dry in the air.

Toe-post sandals need toe socks

A sandal with a post between the big toe and the next one needs a sock with toe sleeves. Injinji makes toe socks as thin liners and as midweight trail socks; a liner is the thinnest under a sandal strap.

Strap sandals: thin and quick to dry

A lightweight sock with light or no cushion sits flat under the straps. Merino feels warm on a cool morning; a synthetic dries faster after a crossing. Avoid full cushion: it bunches under straps.

Cuff height with sandals

An ankle or quarter sock keeps grit off without much fabric; a crew covers the lower leg on brushy trails and cool evenings.

When to go without

River walking, heat and wet days: bare feet in sandals dry in minutes, a wet sock does not. Carry a dry pair for camp.
