“I bought my first pair of these almost 15 years ago from a man in an rv at Atlanta Motor Speedway. I still wear those same two pairs today. They have been to the highest point in the US and the lowest. I finally bought two more pairs and I bet they last just as long.”

“As a power lineman, often working 16 hours days in the most extreme weather environments, I've worn wool socks for a few years now. Granted they were better than cotton or synthetic socks, but still, by mid afternoon my feet have ached with discomfort. On a recent storm break, I ordered two different brand's alpaca socks to try. The Alterra prevail 9" sock has totally changed the game of footwear for me. For the first time in years I have not been racing to rip my socks off as soon as the boots come off at night. Count me a return customer.”
