  • family owned & operated, since 1991
  • comprised of 2% spandex, 17% nylon and 81% certified organic cotton

Quality Materials. Sustainable Process.

Choosy. Meticulous. Uncompromising. When it comes to our materials and manufacturing, these all apply. We start with the highest quality materials, like organic cotton that is dyed with low-impact dyes. Our certified organic cotton is grown on farms in the Southern U.S. by farmers we actually know. After harvest, our cotton travels to the Carolinas where it is spun and dyed before arriving at our mill in Alabama.
We knit socks in very small batches at our family owned and operated mill. Our team of ten (including Mom and Dad) run the manufacturing process from start to finish. And, because our entire operation is under one roof, we're able to constantly monitor quality through each step of the process, minimize waste and deliver a stellar product. We do it all because we know a better process makes a better sock. 
We like to keep it all close to home. Our packaging, labels and marketing materials are printed within a small radius of our mill in Alabama and Georgia. 

Giving and Recycling. Our irregular socks are donated to homelessness shelters and community organizations in Alabama.

We have some socks that are not fit for donations. These, along with any manufacturing waste, are repurposed or recycled. When recycled, these are transformed into fiber used for carpet padding in the automotive industry. 
We can recycle your old socks too! For more info, please see our zkano Recycles page.

    Exactly what I expected.

    My only wish would be that the size spread was smaller… 8-13 means I need to stretch them more, which makes them thinner. My hope is that they will last long with being stretched

    Janise Cross (Middletown, US)

    Purchased a 1 year ago for myself and my husband. Loved the fit, comfortable to wear, and durable doing yardwork. Very happy with Zkano socks especially since its cotton to the manufacturing is done all in the USA and not from a foreign country. Our family loves Zkano socks and a will definitely buy again!

    Happy Feet

    As with many people in the United States, I have realized that investing in America is vital to our growth. I searched for socks that were manufactured here in the US of A. I was fortunate to find Zkano, a family owned company that strives to produce awesome products. I recently ordered for the 3rd time. The quality of these socks are tops. They are extremely comfortable. My feet are happy!

    Great socks

    Very happy I found this company, these are great socks. It’s unbelievable how difficult it is to find mostly cotton socks but I finally did. I work construction and my feet stay hot; cotton socks I’ve found help tremendously and I finally found some worth reviewing. To say I’m pleased with these is an understatement. Zkano will be my go to for socks from now on.

    Crew socks

    We finally found some socks that fit my husband and stay up. Thank you

    Ann Koenig (South Windsor, US)
    Love these socks!

    Suffered a broken ankle resulting in bone grafts which enlarged my ankle and instep. Every other sock I tried was tight around that area, particularly late in the day when it seems to swell a bit. These socks have enough room to accommodate that issue and are very comfortable. I will be a repeat customer!

    Barbara Gross (Midlothian, US)
    5 stars!

    Love zkano socks. Starting with the knowledge that the land where the cotton is grown is being cared for in a beautiful way to the fact that they are fully made in the USA and finally that they are comfy, stretchy, and long lasting. Go Zkano! Go organic farming!
