  • Some jobs are more critical than others, jobs where nothing can be left to chance. When you’re operating at the highest level with stakes to match, you need equipment you can always depend on. That’s why FITS® worked directly with a US Special Forces elite operator to develop the Jon sock. It uses the highest quality materials with extra support in the foot, heel and toe. It’s made to take a beating and comes with a patriotic pedigree to match your own.

    • Our patented Full Contact Fit® hugs the contours of your foot and stays put so there are no loose socks to rub you the wrong way.
    • Crew height rises just below the calf.
    • Extra cushioning in the heel, toe and the arch.

Always reliable

I recently purchased more Fits socks. They never disappoint me with the fit and quality. I will be back for more!



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.
