About ONDO

ONDO is a relatively young company – founded in 2020 by Daniel Shim. Daniel’s vision was to reinvent a no-show sock. And he did it. Thanks to unique technology, ONDO delivers the highest quality no-show socks.

The company is very transparent when it comes to manufacturing. They use innovative fabrics that are traceable all the way to the seed. Also, they are committed to ethical manufacturing therefore all ONDO suppliers have proven track records.

There’s a sustainability part, as well. ONDO no-show socks are made with 62% certified organic cotton combined with innovative fibers for a stylish look. Last but not least, ONDO donates 1% of their revenue to help college students get professional-looking apparel that will help them succeed in interviews.

ONDO Socks Review

ONDO offers a range of no-show socks for everyone. The socks are made from high-quality materials such as organic cotton and merino wool.

The company offers socks for yoga, pilates, low-cut no-show socks, organic cotton, and merino wool no-show socks.

The socks fit well for both men and women, and the size ranges from extra small to extra large.

Thanks to responsibly sourced materials, the socks are extremely comfortable. The unique ONDO technology prevents socks from falling off and ONDO takes this claim very seriously. In fact, the company will give you your money back if the socks fall off.

Speaking of downsides, the only complaint I could find is that the main seam at the toe can be slightly uncomfortable for some people.


  • Extremely comfortable
  • Made of high-quality organic cotton and merino wool
  • Ethically manufactured
  • Wide range of no-show socks to fit everyone’s preferences
  • The socks don’t fall off


  • The main seam at the toe can be slightly uncomfortable for some people

Organic Cotton No Show Socks

Made from organic cotton and innovative aerolight fiber, these socks are incredibly comfortable and breathable. The aerolight fiber also wicks out sweat. The lightweight material offers fast sweat absorption and evaporation to dry quickly while you wear them.

The socks don’t slip off thanks to a specially designed and patented silicone feature. Now, here’s probably my second-favorite feature (obviously the no-slip is No.1) – the socks feature double layered toe. Double layer toe offers extra protection to extend the life of your socks. Forget about the annoying toe holes.

Organic Cotton No-Show socks are made of 62% Organic Cotton, 32% aerolight Polyester, and 6% Lycra.

They are designed in New York, carefully developed and tested in South Korea, and ethically manufactured in Vietnam. The socks come in many different colors and six different sizes – XS to XL.

Speaking of care,  you should wash them at or below 30°C (86°F), don’t bleach, iron, dry clean or tumble dry them.

Low-Cut No Show Socks

ONDO Low-Cut No Show socks are perfect for wearing flats, loafers, and espadrilles since they are shaped in a special way to stay hidden while wearing your favorite shoes. Just like other ONDO socks, they are super comfortable and breathable.

Low-Cut No Show socks are made from a unique blend of certified organic cotton and innovative ‘aqua-X’ nylon fabric meaning that your new sock has heat-cooling, UV-protection, and moisture-wicking features.

The body of the sock is made of 81% MIPAN aqua-X Nylon and 19% Spandex while the bottom is made of 70% Organic Cotton, 25% aerolight Polyester, and 5% Spandex.

Here’s what one of the customers says about Low-Cut No Show socks – They do exactly what they should. They fit well, they stay in place, and they keep my feet dry. FABULOUS!

Yoga/Pilates Socks

If you slip in our socks while you’re doing yoga or Pilates, we’ll give you your money back. Seriously.

After reading this on their website, I had to order a pair for my wife who often practices yoga.

The tech fabric prevents sliding or slipping on hard surfaces and toe holes allow maximum movement control and a strong grip.

The body of the sock is made of 66% Tactel® Nylon and 34% Lycra. The LycraSport fabric offers comfort, stretch, and durability during workouts.

Needless to say, Yoga/Pilates socks feature no-slip technology just like other ONDO socks. Also, they are breathable and reflect 99.9% of UV rays that penetrate the garment to reach your skin during outdoor activities.

The bottom of the sock is made of 40% Nylon and 60% Spandex.

Merino Wool No Show Socks

Merino wool offers numerous advantages: It provides good insulation, transports moisture, it doesn’t itch, smell or crease much. Also, it is lightweight and keeps its shape.

Hope you understand now what makes this no-show sock so amazing. It’s made with the finest renewable, biodegradable Australian Merino Wool and it is sooo soft.

The great thing about Merino wool is that is machine-washable and an excellent thermoregulator for all seasons.

Merino Wool No Show Socks are made with 75% Australian Merino Wool, 19% COOLMAX® Polyester, and 6% Spandex. This combination makes the socks super comfortable and breathable.

Besides, the well-known No-Slip feature, Merino Wool No Show Socks feature double-layered toe protection to extend the life of your socks.


Besides no-show socks, ONDO offers Premium Mesh Laundry Bag as well. Like any other laundry bag, the purpose is to keep your socks in one place and prevent shape distortion.

What makes this bag slightly different is that it’s made with a proprietary recycled-polyester blend designed and made in Korea.

Also, they have a YKK zipper that comes with a protective pouch that reduces clunking during laundry.

Here’s how different Premium Mesh Laundry Bag is compared to others according to one of the buyers – I’ve gone through many laundry mesh bags in my life. This one is hands down the highest quality. The honeycomb mesh and unique oval shape allow thorough washing and it’s extremely durable.

Shipping and Return Policy

ONDO is currently shipping to U.S. and Canada. The company will open up orders to other countries shortly. The shipping is free for orders over $50.

If you’re not happy with your ONDO socks, you can request a refund if the product is unused and unopened within 30 business days.

Speaking of No Slip Guarantee if ONDO socks fall off while you’re walking in your shoes, ONDO   will give you your money back.

Customer Reviews

There are over 10.000 reviews on the ONDO website and most of the reviews are 4 and 5-star ones. Out of 3000 reviews on Organic Cotton No-Show Socks, 1% of them are 1-star reviews.

But I didn’t want to jump to conclusions only based on the reviews on the company’s website. I searched online and I found an interesting topic on Reddit 6 months ago – Has anyone tried Ondo no-show socks? There are many comments and not a single one is negative about ONDO socks.

People who posted comments love the durability, material, and how comfortable the socks are.

And of course, they didn’t fall off. Ever.

Speaking of negative reviews, I found a couple of them. Customers are mainly unhappy about the size. The size they ordered is too small.

Some of them even claim that their socks got holes after a few days.

The bottom line is that over 90% of reviews, all over the web, agree on one thing – ONDO makes fantastic no-show socks.

Is ONDO Worth it?

If I offer you a no-show sock made of high-quality, innovative materials, that is breathable, versatile, comfortable, and never falls off, you’d just buy it without thinking. But if I say that each sock is ethically manufactured, that each piece of material is responsibly sourced, and that 1% of each sold sock goes to help students look professional in the first job interview, you’d stick to that brand forever.

As I mentioned before, when I find a good no-show sock brand, I stick to it.

ONDO is the one.
