Love my FITS

I've abandoned wearing any other brand of socks. FITS keep my feet fresh. And I love the colors!

No-show Runner

Very good for use with my dress-flats and dress-walking shoes. For bulkier-style shoes, though, I prefer footwear that covers the ankles. I have been pleased with all your products. Thank you

What socks that fit?

I wear a ladies size 5 shoe. Everyone in my situation knows a 6-11 one size fits all doesn't come close to working. The heel is up at your ankle. So I say thank you Fit for using some common sense logic in making such an essential item

Love the brand!

I love the brand and their socks in general. These socks didn't have enough cushion for me personally. I won't buy more of this style but I will definitely buy more from FITS.

Best socks

These are easily the best socks I have ever purchased. Yes they are expensive but worth the money !



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.
