“I use Conquer socks for work in the summer. These are worn inside my muck boots while accomplishing farm chores. They prevent blisters and chafing while staying cool. They also stay pulled up since they are over the calf. Many shorter socks simply get worked down by the muck boot. I have had a pair of these in service for 6 years and just today made my first warranty claim as a small spot on the toe finally wore through. I can’t believe the American made quality of the socks! Other supposedly “Darn Tough” brands haven’t survived more than a year on the farm. These were in use nonstop (except for laundry breaks of course) for 6 years. There is not a better deal in the sock market. Altera is the best by far.”

“An absolute perfect sock for HUNTING!!! I used to cut hunts short because my feet would get to cold. I used warm boots, double socks. You name it. Until i found a sock that actually wicked by sweat and warm my foot at the same time. Im so thankful for these socks. I literally was able to buy myself more time in the woods.”

“I've been wearing Altera socks for about 8 years now and thought I'd try a heavy duty version to go with my work boots during the winter. All I can say is, WOW, I wish I had bought 6 more pairs so I could wear them every day. These are now my all-time favorite socks. Very soft. Very thick. I have wide feet and they fit perfectly.”
