Always come back for these

This is my third time buying from Flat Socks, and they're still consistently good. I first tried the leopard print flat socks a while back and loved them. This time I got a bundle of the solid black and a new floral pattern. The quality hasn't changed; they still hold up well and keep my feet comfortable and odor-free. Shipping was quick again, just like my previous orders. They've definitely become my go-to for all my slip-on shoes.

Easy to use, worked well

Bought the solid black flat socks. They were easy to trim and fit my shoes. They stayed in place all day. No foot odor, which is great. Good product.

Pretty comfy liners

Got some of the microsuede flat socks to try out. I hate how regular no-show socks always slide down. These actually stayed put, which was a nice surprise. Trimming them was easy enough. My feet felt good all day, no sweating. Plus, they were machine washable, so that's a bonus. It was a good experience.

Good idea, decent product

I ordered a pair of the solid black flat socks and a pair of the heather grey. They arrived in about 5 days, which was fine. The trimming process was pretty straightforward, and they fit well in most of my shoes. I liked how they felt, much better than traditional no-show socks that always slip. However, I noticed the solid black pair started to show some wear after a few washes, a bit sooner than I expected. Overall, they're a practical solution, but I hope they improve the durability a bit.

Detailed thoughts on Flat Socks

I purchased several pairs, including the solid black flat socks and the terry cloth flat socks, to replace my usual no-show socks. The ordering process was smooth, and the website was easy to navigate. Delivery took about a week to the Midwest. Upon arrival, the packaging was simple and efficient. Trimming them to fit was intuitive with the guides provided, although a sharper pair of scissors made the job easier. I found the terry cloth ones particularly comfortable for everyday wear, offering good cushioning. The antimicrobial claim seems accurate, as I haven't noticed any odor issues. They stayed in place well, even in my more active sneakers. One small observation: the thickness of the terry cloth pair made some of my tighter shoes feel a bit snug, so that's something to consider for different shoe types.

Good value with the bundle

I was looking for an alternative to no-show socks and found Flat Socks. I decided to try a bundle deal to get the best price, which included a pair of the heather grey and a pair of the checkered flat socks. The discount made it feel like a really good deal. They fit well after trimming, and my feet felt comfortable, definitely a step up from what I was using. For the price I paid, I felt like I got good value for my money, and they seem like they'll last a while.

Do these really help with foot odor? My shoes sometimes get pretty stinky and I'm desperate.

L Leah 2 weeks ago
OMG yes! I was skeptical but they actually do. My sneakers used to smell terrible after a long day, and now it's way better. Seriously, give 'em a try.

They have some antimicrobial stuff built in, so yeah, it helps a lot with the odor. Plus, you can just toss 'em in the wash. Much better than trying to clean your actual shoes all the time.

Hey everyone, thinking about getting some Flat Socks. Do these things actually stay put in your shoes or do they slide around like crazy?

N Nancy Moore 5 days ago
Mine stay in place really well! I've worn them in a few different pairs of flats and sneakers and haven't had any issues with them bunching up or sliding.

Yeah, they have some kind of grippy stuff on the bottom, I think. Haven't had a problem with them moving around at all. Way better than those stupid no-show socks.

Has anyone compared these to Gekks? Are Flat Socks better or is it pretty much the same thing?

A Aaron Hernandez 1 week ago
I've used both. Flat Socks feel a bit more cushioned to me, and I like that I can trim them myself for a perfect fit. Gekks are fine, but I prefer the Flat Socks overall for comfort.

Definitely Flat Socks! Gekks were okay but didn't last as long for me, and the odor protection on Flat Socks seems way better. Plus, machine washable is a huge plus.

Just wondering if anyone has tried using a discount code AND the bundle deal together? Trying to maximize my savings here lol.

H Hannah M. 1 month ago
From what I remember, it's usually one or the other. They do automatic discounts on bundles which is cool, but a separate code probably won't stack on top of that.

Nope, you can only use one promo code at a time. I tried it last Black Friday, didn't work. The bundle savings are pretty good though!
