About Altera Alpaca

At Altera, we believe your gear should work as hard as you do. That’s why we’ve redefined performance from the ground up—starting with socks. Using the natural power of alpaca fiber, we’ve created socks that outperform wool and synthetics in comfort, durability, moisture control, and temperature regulation. Born in the rugged fields of Kentucky and tested on trails, slopes, and job sites across the country, Altera socks are built for wherever your feet take you. We source high-quality alpaca fiber and craft our socks in the USA, combining time-tested natural materials with modern innovation. Our commitment doesn’t end with the sock. Every pair is backed by our Unconditional Lifetime Warranty—because performance should never be a question mark. Whether you’re hiking mountains, working long shifts, or just chasing comfort, Altera helps you go further with socks that feel better and last longer.
