  • 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.

    Great socks

    I’ve been loving these socks for a few years now. Love how thick and cotton content.

    Karen Messer (Portland, US)
    Zkano socks of all types

    We have bought Zkano socks for years now. They are the best. Always satisfied with Zkano socks purchases.

    Ashley Gibson (Trenton, US)
    Unmatched quality. 10+ yrs

    My husband brought home zkano socks over a decade ago. He bought them from the manufacturer's location while he was servicing some of their equipment. I had never heard of them, even though they're a local company. 10 years later, he's started walking holes into the heels and the seams are beginning to come unthreaded. I bought a different, less expensive brand, for him at Christmas last year. Those began falling apart months after. I rounded back around and bought him more zkanos. While doing laundry tonight I had to laugh, as we're still cycling through decade old zkanos socks with the new ones, and tossing other brands nearly every week as they come apart. 💙

    These make a great gift!

    I ordered 4 pairs of zkano socks for a lady friend of mine as a gift. Two of the Merino Wool / Organic cotton socks, 1 pair of the " on the farm " and a pair of the " night owl"

    Fabulous Socks Made in USA!

    First things first-fabulous socks, great cushion, not thin like so many imported brands sold at War-Mart, Target and the like.
    Second-less lint between my toes, even before washing the first time! Amazing
    Last-the obvious...my hard earned dollars are supporting an American family from the south. Being a southern girl, born and raised in Mississippi, I love to support another family business making it happen below the Mason-Dixon Line!
    Summary: Will definitely recommend to family and friends and will purchase again.

    Extra padding

    I like the "tread - heavyweight organic cotton crew socks" because I often just walk outside for a quick breath of fresh air, without bothering to put on my shoes. The extra padding on these socks makes them last longer under my treatment.

    Barbara Gross (Ennis, US)
    My husband loves these socks

    My husband is an auto tech and he loves these soft yet durable socks.

    Allen Ray (Asheville, US)
    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

    Jan C (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!
