Didn’t work for me

Uncomfortable. Tight. Too thin. Gave them to my wife—she wears them but would not buy them. These socks may work for others but not for me.


No way is this an invisible sock. It comes up too high. First time I am not in love with FITS. I guess that was their solution for no slip.


Hi Yvonne. Thanks for the review! I'm sorry you don't like the Invisible sock. Please reach out to, and a customer service rep can help with a return. Have a good day!

My favorite! Hugs your arch

My favorite! Hugs your arch and they don’t slip or bunch up!

No slip! No problem!

Fits has done the impossible! They’ve created an invisible sock that actually stays in place on one’s feet and do not slip even after wearing for several hours. I’ve tried several different brands over the years and had never found a pair of invisible socks that didn’t slip off my heel after only a few minutes of wearing. That all changed when I purchased my first pair of Fits. I am a very satisfied customer.

For the Price I...

For the price I was disappointed. The fit was not great and the fabric just doesn't feel like the shoe liner I was hoping to receive.


Hello Jeanine. Thanks for the review! I'm sorry you don't like the fit of the Invisible style. Please reach out to and they would be happy to help with a return. Thanks!

Love them

Just what I was looking for in a summer sock. I love Fits Socks. Thank you.

Fantastic sock

So, so glad to have finally found a sock for loafers and boat shoes that doesn't slip down in the heel. This is the best invisible sock I've ever used, and I've tried all the big brands (and all the department store names you can imagine). This is simply the best one I've ever used. I'll definitely be buying more. Thanks FITS!

Socks don't stay on foot

The heel annoyingly slipped off within minutes of walking around in my loafers. These socks lack the rubberized heel stays other brands use. Would not recommend.


Hi Scott. Thanks for the review. I'm sorry you are having trouble with your socks. Please reach out to and they would be happy to help.



The Perfect Fit Starts With the Right Size.

Your sock size shouldn’t be a guessing game. Our socks range from small to double XL, but the best way to know the perfect fit for you is to match your shoe size to the chart on the left. That way, you’ll know the size you select will give you the fit and feel you expect.

Between sizes? Go with your gut, but rest assured that your socks will still fit great. If you receive your order and find yourself wishing you’d gone up or down a size, just let us know. We’ll happily send you replacements for your preferred size.

Concerned about laundry mix-ups? All FITS® socks are coordinated by color and size, based on the colors you see on the size chart. So, you won’t have to worry about mixing up your sizes with the other FITS® wearers in your home. (But stray socks mysteriously going missing in the dryer? Unfortunately, we can’t help with that.)

Questions? Let’s talk.
