The trail changes.

Your socks have to keep up.

A cool start can become a warm climb. Dry trail can turn wet. A short scramble can become an all-day push. Your socks sit between your foot and every mile of that terrain.

Altera hiking socks are built to help keep feet comfortable across changing conditions, draw moisture away from the foot, and stand up to repeated wear — without losing shape after the miles you have to think about.
