FITS quarter

I am extremely happy with all of the FITS socks. All very comfortable and warm. This one was new for me and it is a nice alternative to warmer weather.

Great socks

Really love all of my fits socks. No shows to otc snow boot. They are top of the line in comfort and durability.

Fits is a beautifully made sock. However, like many other sock designs today, the elastic at the top is too constricting, actually cutting off circulation in feet and legs, leaving a substantial indentation

Best socks ever

I love Fit socks. First got them for running and have been enjoying them for work and play. I'm on my feet alot at the fire department and these socks perform. My feet don't overheat in my leather boots and the socks stay up when I switch from duty boots to my structure boots. Would absolutely recommend these socks to anyone that will listen.

Sock already has holes in it

Sock wore out in 3 months. Very disappointing.

Nice socks

High 70% wool content socks are warm, manage moisture well and are the right thickness for best balance of comfort. Nice blue color. These socks fit somewhat like the trail run socks previously made by North North Face, i.e., they seem to run slightly smaller in the toe/front end of sock than other sock makes (at least for me) but they do remain snugly yet comfortably in place while running. These socks work well for trail running in cool weather. Would recommend these socks for any running activity.



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.
