  • There’s a reason they call it a “happy” medium — because with slightly more support, but a still barely-there feel, our Micro-Light Runner has the best of both worlds. With subtle cushioning and a slightly higher cut, your feet will definitely be happier.

    • Our patented Full Contact Fit® hugs the contours of your foot and stays put — ensuring loose socks won’t rub you the wrong way.
    • Mini-Crew height rises midway between ankle and calf.
    • Toe and heel cushioning.

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.

Our family’s favorite socks.

My 11 year old who is very sensitive to the way things feel is in love w these. I purchased 4 pairs of the same pattern for him so when he loses one we still have matching socks to wear. :)

Fantastic running sock

This is one really good sock. Nice fit, great support where it matters and comfy as all get out. The other socks that I have sit languishing in the drawer now.

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.
