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.
All our socks are made with 18.5m superfine knit, suit-grade performance Merino wool.
Our custom blend of man-made fibers selected for the best breathability and fit.
A friend of mine recommended these socks. I didn't believe the hype, but these socks are awesome! They actually stay on your feet! I've tried so many different brands of "non-slip invisible" socks... none of them stayed on all day... these socks do! My feet were sad before...now they are happy! You need these socks
Excellent no show socks that stay in place
Great socks as described. Stay put on on your foot all day.
Fits perfectly, didn't stretch out or dip behind the back of my shoe. Quite comfortable. It was exactly what I needed. Will be getting more for sure
I have tried them all. FITS has it figured out. The only sock that keeps it’s shape without the sticky heal. I always assume invisible socks last a year at best, this is my third order with FITS and I have pairs that are almost 2 years old. Obviously they aren’t the same as new, but not complaining in the slightest given other brands I have tried last around 3 months tops.
The Fits Invisible sock is the best I’ve ever tried. Other brands will not stay on my foot, but the Fits stay all day and are very comfortable. I love all Fits socks!
I discovered Fitts socks last winter. The invisible socks are well made, extremely comfortable and never slide down in your shoes, Our children look forward to receiving Fitts socks this Christmas.
Love these socks
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.)
Sock sizes are typically measured in inches, not by your shoe size. So, a sock size 6-8 will comfortably fit someone whose feet are between six and eight inches long. However, at FITS®, we make it easy for you to choose the ideal sock size without having to measure your foot. Simply use our sock size conversion chart based on your shoe size to select the right fit for you.
To measure your foot for socks, measure the length from the heel of your foot to the tip of your longest toe. The measurement in inches correlates to your sock size. For example, if your foot is 10 inches long, a sock size 9-11 should fit you comfortably. At FITS®, you can skip this step and find your sock size based on your shoe size using our conversion chart.
The sock size conversion refers to sock size compared to shoe size. While all companies may vary slightly on which size socks to purchase based on your shoe size, you can always measure your foot to find the right fit for you.
Because sock sizes are determined by the length of your foot in inches vs. your shoe size, shoe and sock sizes differ. The FITS® sock size to shoe size conversion is as follows:
Knowing this makes it easy to choose the ideal sock size based on your shoe size without measuring your foot.
Sock sizes typically don’t correlate with age. For kids, age can be a general indicator of what size sock they’ll need, but everyone is different. An adult sock size 9-12 fits anyone whose feet are approximately nine to twelve inches long. For kids’ sock sizing, check with the company to find exact details to ensure your little one gets the perfect fit.
