What Size Do You Need?

Perfect as both a sock or a liner, these sport Over The Calf (OTC) socks are favored by NHL and minor league hockey players. The arch and ankle support zones keep the sock in place. While the mesh ventilation zones aid in air circulation.

  • Natural moisture-wicking materials with ventilated mesh keep feet dry and blister-free.
  • Flat knit design for a foot-hugging low profile fit with integrated toe seam for comfort.
  • Inhibits foot odor.

Why Bamboo Socks?

Bamboo is an ecologically friendly plant to farm. Unlike other materials, bamboo viscose performance attributes are natural, so there is no need for chemical additives or fabric conditioners. Bamboo viscose has a silk-like feel and is ultra-soft against your skin, which reduces friction and makes for really comfortable socks. Learn more...

    I love these socks so much for their superior comfort and moisture wicking abilities. I bought other styles for my wife and Dad. I love that they are made in the USA. I fully recommend this brand to replace all of your socks. I will be a consistent repeat customer.

    Great soccer sock liner for high school son

    Posted by mfin on Jun 23rd 2021

    My son has been getting blisters quite often during soccer season and I did some research and found these socks. I pinged customer service about which socks to buy and they recommended these as they are thin and can be worn underneath his game / practice socks. So far he loves them and no blisters.

    Best comfort

    Posted by Tree on May 27th 2021

    I have been searching for a sock that would help keep my leg eczema at bay, while working in a fab. I found ecosox and gave them a try. I am 100% satisfied with these socks. The socks are very comfortable on my feet and legs and are moisture wicking. No break outs yet. Thank you Ecosox.

    Best Soccer Socks

    Posted by Laura McCaffrey on Oct 15th 2020

    These are my son's favorite socks hands down. Unless he has to wear his blue or red game socks he is in these. What 13 yr old only asks for socks for Christmas? That's how much he loves them.

    I was happy to find your booth at The All American Quarter Horse Congress in October. My son works construction, and it is very difficult to find comfortable, affordable socks for him. He is so pleased with their comfort that he had me order 10 pairs for when he returns to work. Thank you!!
