Most Comfortable Socks EVER!

Great Fit! So comfortable that you don’t even know you’re wearing socks! Started with your ski socks, love them-all day comfort, and this Ultra Light Runner is another Great Find!

Ultra Light Runners

These are my favorite running socks. The fit is perfect and the merino wool blend feels good against my skin and keeps my feet dry and comfortable. You can find cheaper running socks but they don’t last as long as FITs socks. I let my sister borrow a pair and I was afraid she would never give them back.

The best running socks.

I’ve worn Fits light hikers for years and recently tried the ultra light runners. They’re perfect. Comfortable, breathable and you can feel the quality.

Ultra light sock

I absolutely love my socks. They’re just right there not too thick they’re not too thin they give me the support that I need. Let me know when they go on sale so I can get some more.

Great Socks

These are really high quality socks, very comfortable and you can tell the material is a step up from what you will find off the shelf. I will be buying more.

Sizing

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.
