"I have been out in the field on exercise all this past week (wearing Altera socks the entire time). I was extremely pleased with the ability of the Prevail socks to keep my feet warm while living outside in -20 degree celsius temps.They are the warmest socks by weight that I have ever used."
"The Explore is a sock that will work well for many activities (I love it for cool weather cycling). It will keep the user dry and comfortable and blister free.
This is a great sock!"
"I was really surprised at how comfortable they were compared to our standard issue socks. We hiked over various terrains, including hiking up and down ridgelines. These Altera Socks protected my feet, also preventing any blisters while scaling over rough terrain."
