“I use these for running in the winter or even in chilly spring/fall conditions. They regulate temperature well so I’m not cold at the beginning of the run or too hot during the run. Additionally, they provide excellent padding in my thin 0 rise “barefoot” shoes. There are tested for many miles (30 miles weekly for months on end). Also, they don’t stink afterwards.”

“Love them! I was hesitant to purchase the no show socks because in the past, any no show socks would slip down and bunch up. These socks stay in place and are so comfortable! As a long time Altera Alpaca sock wearer I would highly recommend these socks as well as all of their socks. Great product and great customer service.”

“Been wearing these for now a few weeks. I could tell a difference on the first few steps. Ive walked in rain storms with these and I've walked as much as 10 miles in one day. I wear them for work and my morning walks. These are awesome socks for sure. Will be buying more.”
