Q: Do these socks lay flat in the shoe or they wrap around the foot
submitted by Roro - 1 month ago
A: Hi there,
Thank you for contacting Flat Socks.
FLAT SOCKS® lay flat inside the shoe — they do not wrap around the foot like traditional socks. They’re designed as a thin, low-profile layer that sits smoothly between your foot and the shoe’s insole.
This helps to:
Reduce friction and hot spots
Add light cushioning without bulk
Work well in snug shoes where regular socks may feel tight
They’re also customizable — you can trim them for your preferred fit, so they work across different shoe styles and sizes.
FLAT SOCKS® can help keep shoes fresher by creating a moisture-wicking barrier between your foot and the shoe’s insole. They stay in place with a subtle grip on the bottom, so they don’t shift. They’re also machine washable for easy care.
Please let us know if you have any other questions — we’re happy to help!

Q: Are there low profile enough to use in ballet flats or Mary Jane flats?
submitted by Chri - 3 months ago
A: Hi there - thank you for reaching out with your question, and for being a FLAT SOCKS customer. We really appreciate you taking the time to check fit details.
FLAT SOCKS range from 1/8" to 3/16" in thickness, depending on the material. The micro-plush, BK mesh and cotton fabrics are the thinnest at 1/8", while the micro-wool, and curly pile are slightly thicker at 3/16". If your shoes are already a snug fit and you’re unable to remove the shoe’s original insole, FLAT SOCKS may not be the best match for that particular pair.
If you feel there’s a little room left in your flats, we suggest starting with the least thick styles (micro-plush, BK mesh, or cotton) and trimming gradually along the guide lines. Fit can vary by shoe. Do let us know if you have any more questions.
Thanks again for your question and for choosing FLAT SOCKS.

The Actual Best
I haven’t found a pair of no show socks that stay up so I figured I’d try these. They are perfect!!! Comfortable and my shoes/feet don’t smell.

Check before you leave
The Flat Socks are fine,but I ordered 2 of the gray. My mistake for not checking before I left the store because they gave me 1 gray and 1 animal print.

Too Narrow and Too Small
These do not fit as described. I bought them for my boyfriend's boots. They are a size 10 and these inserts are way too small. Total waste of money. In the U.S., a women's 12 is a men's 10. These are marketed as fitting a women's 11, which is a men's size 9!

Too narrow
Love these but they are very narrow. They do not fit the entirety of my shoes width wise. So if you have wider feet, just keep this in mind. Otherwise, they are very soft and comfortable and easy to trim to fit the length of your shoes.

Flat Socks Rock!
These are the best. They really provide a comfortable cushion and keep feet dry and odor-free.
These are really cool! I received these for free in exchange for my honest review.. and truth be told I was a little skeptical about them. But, after some use I can confidently say I’m a believer! They are easy to trim down to your shoe size, and once in your shoe are quite comfortable. I’ve worn them in crazy hot and humid temps and love that I don’t have to battle with no shoe socks slipping down around my foot, yet my feet don’t get sweaty and stinky like they do when I go without socks in my shoes. Best of all, they are washable (and hold up well!). I highly recommend and am getting more for family members. A truly unique and smart invention.
First off, these are not "socks" at all! And that's what cool about them. They're more like a comfy sock-lined shoe insert. Cutting them down to my size was really easy and simple. I was a little worried they would make my converse feel tighter, but they feel great. I'm so glad I won't have to wear socks in the summer! I use them with my toms too. I wouldn't recommend them with running shoes because there's no protection on your ankles so if it's rubbing a lot, you're stil gonna get blisters.
I am quite surprised at how well these inserts work. A flat sock is an interesting concept. When I first got it looked just like an insole but I was so wrong, mind you it does go in your shoe like one but they feel good and breathable in my work flats. I don't have any problems with smell or sweat wearing these which is a big deal since we live where it's hot. They are easy to measure and fit any shoe. The best part is that they are remove able and can be placed from one pair to the next easily. They wash well, I have only air dried them, I wouldn't recommend putting them in the dryer. The best part about these little flat socks is that there is no slippage around your feet and you really can't see them at all!
These were comfortable and didn’t make my feet sweat. They were a little long for my shoes but very easy to trim down. I would be comfortable putting these in any shoe, especially women’s flats. The backs have a texture that makes them not slip around inside your shoe.

I don't understand the value of these "socks." The selling point is that with them you can go sockless. However, the shoes I'd like to wear sockless irritate the top of my toes and back of my ankles, These insoles do not protect your feet in these areas. Most of my shoes already have pretty comfortable insoles. I am glad that I have a really sharp pair of scissors to cut the Flat Socks to size as with standard scissors it would have been tiring on my hands. I have placed them inside my Dansko clogs and they do make them a bit more comfortable but save your money and skip this product.
I had never tried these type of socks before and was a little skeptical. They were easy to trim. I used the size guide to trim them and the size was perfect for my shoes. The tops are really soft, and the cushion makes my shoes much more comfortable. I'll definitely be getting more pairs.
First of all I want to say I am guilty of putting on my slip on shoes with no socks whatsoever and that's a bad habit of mine. So this product is amazing to me. It's basically a shoe insert that you can put into different shoes and remove and switch to other shoes. You can toss it in the wash when it needs it and use it over and over. It feels good on my feet. No complaints there. You can even cut it to size to fit your shoe size. Overall a really neat product versus wearing no show socks etc.
The idea for these is great. I just didn't love them. I hesitated to cut the socks because I didn't want to accidentally cut too small. They were also a bit tough to get properly in the shoe due to the rubber on the bottom to help them stay put. If you use them in shoes that currently fit, it makes the shoe fit a little too snugly sometimes. So, good idea, but not wowed.
Girlfriend was excited by these since she hates wearing socks, they were easy to trim to fit her shoes and were rather comfortable for her feet. She loved them. Having said that, these smell horrible when you first get them. just awful. Separate them and let them air out for a few days before using them or you will regret it. that smell will be all over your feet and shoes.
These turned out to be more of a shoe cushion instead of no see socks but they do serve a good purpose if you like to go without socks while wearing certain types of footwear. They do provide a nice cushion, are washable, and can keep your shoes from getting smelly if you like to wear them without traditional socks.
