Much Better Than No-Show Socks!

"Comfortable and washable. Much better than the alternative!"

Daniel R. (5/5)

Love the freedom

"Love being sockless and not worried about foot oder"

Charlene A. (5/5)

Very Comfortable

"These were easy to fit into my size 10 golf and regular tennis shoes. Super comfortable and easy to remove, wash and put back in."

Duane M. (5/5)

"I love my Flat Socks !"

RaSha H. (5/5)

"Worked great in my bowling shoes"

Matthew (5/5)

Finally, the perfect insole.

"FINALLY! I've been looking for an insole that isn't cheap foam, isn't too thick, isn't too mushy and will give me "just enough" to make my boots and loafers fit perfectly. I've been searching for such a product for (literally) years. Once I put Flat Socks in some custom made boots, I bought 7 more pairs of them the next day. Thank you!"

Jeff R. (5/5)

Amazing. . . . and they work!

"I love to wear shoes without socks but hate how it makes my shoes smell. When I heard about Flatsocks I thought it was worth a try. I love them so much I bought a set for all my shoes!"

Sarah W. (5/5)

"LOVE these WARM Flat Socks for cooler days!"

Sharon (5/5)

Glad I discovered Flat Socks

"The Gray and Beige Micro Fiber Flat socks I wear in my sandals for more support, and they appear to be warmer for cooler temperatures. I like the large or small size option, and the ability to trim them to size. Thanks for having two sizes for adults to choose from. They haven't fallen apart when I wash them so far. My feet do sweat in them in the warmer weather, but it is a blessing not to have to replace them so often and wash them by hand. I have noticed when I put powder on them, the powder stills shows after I wash them. But after all is said, I am glad I saw them on Ebay. Please make available the cotton in large please."
