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.

“While in Glacier on a 6-day hiking trip, I put a lot of miles on them and wanted to see just how long I could go without washing them. Amazingly, after 5 days of hiking and letting them air dry each night, there was zero odor! Not only that, but they easily took any abuseI threw at them. By comparison, I tried another brand of socks recently, and in less that 5 days of use they had already blown out! I am saying within 5 days of taking them out of the package the toes and heel had holes over 1.5” diameter in them. Some companies invest money into creating a high performance product like Altera, while others just spend it on marketing and flooding Facebook with catchy ads….”

“Wore these on a mountaineering trip in Nepal up to 20k feet and just bought another pair for Denali this summer. Perfect for tall 6-8,000 meter mountaineering boots. Zero blisters and super warm.”

“Tried a pair out on my longest hike to date. Highline trail in Glacier NP. Feet were not soaking wet after 8 hours on the trail like they would of been with cotton socks. Best socks I have ever put on my feet.”
