Your Shoe's Best Kept Secret

They never show, never slip around, and they let you rock out with no socks while keeping your shoes from becoming a stinky mess!

heart shaped wool flat socks

Dry Insoles

Amazon Customer

I like that they dry very quickly if my feet are sweating. There's no smell so that's great!! And machine washable is a bonus.

heart shaped paint splatter flat socks

These Work!!!

One Mom One Voice

I put them in my Pickleball shoes & they really work to keep the odors at bay! I bought 2 pairs.

heart shaped black geometric flat socks

Great Idea for Going sans Socks!

William S.

A great alternative for wearing Hey Dudes or similar shoes without socks and not ruining the insoles. My wife loves these.

heart shaped floral embroidery flat socks

Comfortable, Adjustable, Washable

Theryn

These are great, easy to trim down to the right size, squishy enough to add a nice extra layer of comfort and washes very easy. The first pair I got I forgot they were washable and wore the heck out of them. They were pretty gross and about to be thrown out till I saw an ad for them which reminded me they were washable. A quick wash in the sink then washer later, and they are as good as new. I bought 3 more pairs

heart shaped furry flat socks

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.

heart shaped snow leopard flat socks

These Are a Perfect Solution!

Soap

I’ve tried so many different ways to wear slippers, loafers and the like without my socks showing. Always ended up skipping the shoes and going for sandals. These are the perfect solution. All you have to do is take out your shoe lining, use it as a template to cut the new flat sock to size, and put it in your shoe in place of the shoe liner. They wash perfectly are ready to reuse just like socks.

These Give Cushioning

Lucyakers

I volunteer at our food bank and am on my feet for about 6 hours. But it is HOT in AZ and these let me wear my skimpy sneakers instead of the big heavy ones yet still cushion the bottoms.

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!
