Advantage
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.
Performance + Comfort
Moisture Wicking - We understand the discomfort that comes with dampness. That's why our alpaca socks are engineered to efficiently wick away moisture, keeping your feet dry and comfortable even in challenging environments.
Temperature Regulation - Nature's moods can be unpredictable, ranging from sweltering heat to bitter cold. Our socks are designed to adapt, providing warmth when it's chilly and allowing breathability in warmer conditions.
Antimicrobial Protection - We know that hygiene is of utmost importance, especially during extended adventures. Our socks offer antimicrobial properties to help keep your feet fresh and odor-free.
Hypoallergenic Relief - For those with sensitivities or allergies, we've crafted our socks using hypoallergenic materials to ensure that comfort never comes at the cost of irritation.
Durability and Performance - Your gear needs to withstand the rigors of all your activities. Our alpaca socks are not only durable but they can be worn for multiple days without having to be laundered, ensuring they perform when you need them most.
