Invisible Sock
The FITS® Invisible Sock features a seamless, one-piece construction that keeps the sock locked in place without being seen. A dynamic toe box, allows toes to move freely without tugging at the rest of the sock, while a smooth top offers maximum comfort. FITS socks are proudly made in the USA.
Material
Made with fine-gauge, suit-quality merino wool, our materials are blended to optimize odor resistance, durability, breathability, stretch, and moisture-wicking.
Supima Cotton 60%, Nylon 35%, Lycra 5%
Care

Finer Fabric, Better FIT.
Whole Foot Comfort begins with premium fabric. That’s why we ground our knits with a higher quality 18.5-23.5 micron ‘fine-gauge’ merino wool. The kind typically used in luxury formal wear. This gives FITS a distinctly different, and superbly soft, feel unlike any other performance sock. Because no other sock is made like FITS.
All Day Comfort Guaranteed

United StatesNot staying put
Still looking for a no show sock that won't slip off from my heels, this is not it. It doesn't matter if I wear these with sneakers or loafers, heel will come out no matter what.

United States United StatesNo slip!
These are really comfortable and don't slip off at all. Totally invisible, great for slip on shoes. Just ordered more, thanks!
United StatesPerfections
We have tried many invisible socks but none of them are as good as the Fits!
United StatesBest hidden sock on the market
Love the sock but shipping took way too long to get here.
United States United StatesInvisible socks that stay in place!
These are the best no-show/ invisible socks! They stay on my heel without any issues. They also have plenty of toe coverage so they stay in place and don't slide around like other invisible socks. These are easy to wear like any "normal cut" sock and I don't have to fight them or fix them throughout the day. I have them in all the colors!
United StatesDoesn’t slide off
The invisible men’s sock is great for getting the look like you are wearing no socks at all.
