“Currently I am serving in the Army and I am stationed in Fort Irwin where we have a very dry climate but our temperatures vary from hot weather to temperate weather. These Altera Socks protected my feet, also preventing any blisters while scaling over rough terrain. Since wearing the Altera Socks throughout our training environment and in our garrison environment, they are the only socks I will wear. They greatly reduce foot fatigue and prevent any foot odor, even when put through vigorous training exercises and temperature differences. I have complete faith in these socks and would highly recommend them to anyone that works indoors or outdoors. I currently own two pairs, and have chosen to wear them over my previous favorite Under Armour socks. These Altera socks are considerably more comfortable, prevent footwear and again leave your feet and footwear odorless.”

“As an Army infantry veteran I have tried and used many types and brands of socks. I have over the past several years settled on alpaca socks and Altera is definitely top quality and amazing service! The cushion is better than some of the other brands. The fit and comfort is top notch! I suffered a severe back injury while serving that left me with nerve and blood flow issues in my legs and feet. Due to this my feet are very sensitive to blistering and pain. These socks have helped eliminate hot spots and have provided me much needed relief for the long days I still have to work to support my family! Thank you Altera for great socks and great service.”

“As a 22-year retired Army vet, boot socks are a prize possession if you find the right pair. So, I started at the Army PX and picked up a pair of the Altera Alpaca Conquer Lightweight 14" OTC, amazing socks for my transition from combat boots to cowboy boots. Soft, absorbent, and they actually stay up without too much pressure on your calf. Quickly picked up another 2 pair. Gonna be my go-to sock going forward. Easy to understand website. Clear easy navigation, and the links take you where you intend to go. Top notch product getting a top-notch website.”
