See full warranty →maximum cushion for cold, demanding days.
Adventure is built for the days that ask more from your socks: cold starts, heavier boots, long hours, rough terrain, and repeated wear in the field, on the trail, or on the job.

Most Altera customers run a multi-pair rotation — same engineered blend, different cushion and height for what the day demands.
