The Ultimate No-Show Sock

Rainbow FLAT SOCKS in white Converse All Star shoes with rustic background

Other "no show" socks are either "some show" or they inevitably slip over your heel and become a wrinkled mess, or they demand extra time with sticky tapes or removing and replacing shoe insoles, along with frequent adjustments throughout the day. FLAT SOCKS® are literally the simplest solution!

Why FLAT SOCKS®?

no slip

The underside is a super grippy textured foam surface. These things seriously don't budge!

no stink

FLAT SOCKS® create a moisture-wicking barrier that saves your shoes from becoming a stinky swamp!

no show

While you're out rockin' your FLAT SOCKS®, they're your shoe’s best-kept secret!

no stink - odor control tech helps keep feet fresh
moisture wicking pulls sweat away
soft & cushy - supportive foam makes every step comfy
machine washable - throw them in the wash, just like socks

No Sacrifices

While FLAT SOCKS® may look like a shoe insole, they don’t replace your shoe’s insole; they replace your SOCKS! At the end of the day you can treat them like socks, too—throw your FLAT SOCKS in the washer (and dryer) as often as you like!

Traditional socks ruin a great outfit, and “no shows” always show or slip down and become a wrinkled, annoying, uncomfortable mess. FLAT SOCKS® give you the ability to let your shoes speak for themselves. They never show, never slip around, and they let you rock out with no socks while keeping your shoes from becoming a stinky mess!

Effective

Michelle

If you have a child who refuses to wear socks TRUST ME when I tell you these things will reconcile your relationship with that child. We literally made our volleyball playing daughter leave her shoes under the car when we traveled for a tournament because we did not want those shoes in our hotel room or our car 🤣 Since then we switched to FLAT SOCKS and after two days of practice and a full weekend of tournament play in them I can testify to their effectiveness. 👏🏼

Comfortable

Aubree

I love these! They're comfortable and were easy to trim to fit my low top converse!

Highly recommend.

Cat

My son hates wearing socks (and shoes but that's another story). So I have been trying to figure out how to get him to not have stinky shoes. Well, he thought they were weird so I said I'd try them. They are awesome. Soak up sweat and haven't started to smell yet. They were easy to trim to fit and easy to wash. Highly recommend.

Great Invention

Nancy

This is a great invention - I tried all kinds of socks, but they always fall into my shoes and off my heels!

Love These

Dana

I love these flat socks. I always have issues with my no show socks falling off my heel while I'm walking and it's so annoying. With these I don't have to worry about that. They also wash and dry well.

Real People. Real Results.

Better Than Expected

I haven't tried these specific ones (I got 3 pairs) but they are super! I have a shoe that is my go to for slipping on and heading out, whether to throw trash or just a quick walk and the insole just practically disintegrated. Very poor quality. Got these hoping they would help. Cut to fit, slipped them in and man! No problems whatsoever. No slipping. No sticking to a dirty foot. No pulling out when I remove my foot. And so far no stink. And I swear my feet feel softer. Recommend wholeheartedly!

Flat Socks Are a Game Changer!!!

Flat socks are a game changer!! I hated wearing "no show" socks or what they call "hidden liner" with my flats at work. The hidden liner was not so hidden and it drove me crazy! These are wonderful!! They help my shoes fit better while providing the sock like feel while wearing my shoes. The fact that I can wash them and continue using them is a great plus as well. I have a set of Flat Socks in every single pair of shoes that I like to wear "without" socks and it is fabulous!!!

LIFECHANGING

I love everything about these socks -- they're cute, comfortable, and oh so helpful! I have a ton of shoes that need no-show socks, and these have replaced those stupid little socks that always slide down into my shoes. I'm never going back!!

Flat Socks Are Great

Really love the flat socks. They are comfortable to wear, fit in all my shoes, and wash up very nicely. I've ordered more!

Great Product

My husband has feet swelling so regular socks just inflames his feet more. These are great as they can be washed and save on the expense of buying new shoes all the time.

No More Stinky Feet!

I bought two pairs of these. My feet sweat a lot and apparently smell bad. I replaced the soles of my shoes with flat socks and I can't believe the difference! Totally recommend to anyone with stinky feet.

Best Invention - a Must Have!

These are so cute and great to line your shoes so u don't have to wear socks. A little added cushioning for your feet and really terrific if your shoes are too roomy. Highly recommend! I have purchased 6 pairs and you can cut them to your specific size.

Best Socks Ever!!

Finally, a non stinky way to go without socks. These are stylish and comfortable. I purchased several for myself and now my kids and others want some too.

Love These Flat Socks!

Came upon these flat socks at a shoe store and bought them. Since then I have bought 6 more pairs. They are fabulous to put inside shoes that may be too roomy for a better fit and allows for no socks. The added padding is fabulous for comfort too! I hat put them in boots, flats and dress shoes sand they are great! Highly recommend giving them shot! What a great invention!

In Love with These!

I didn't expect this to work so well! They're more than just an insole, but actually work to keep your feet dry and function like a sock, without revealing to anyone that you're wearing them. Gone are the days of socks sliding down inside your shoe.

Flat Socks are Fantastic!

These socks make any shoe more comfortable and can be cut to fit any size. I am on my feet for more than eight hours during work and I have ordered lots of them so that I am able to wear even my boots all day. The patterns are great, too.

I Love Them All!

My flat socks are comfortable and convenient. No more socks in the summer. So far the washing and drying has worked perfectly. Getting more so more shoes will be ready to roll. And it's fun to match my flat socks with my shoe colors!
