Micro Light Performance Trail - Quarter

50 reviews
Size Guide
Light Grey

The Micro Light Performance Trail looks different for a reason. The high cuff is a built-in scree-guard that helps keep out the trail while you're trail running. Below the cuff is a vented lower that increases breathability during highly aerobic activities.

  • 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.
  • Hybrid performance cuff sits between a quarter and a crew height for added protection.
  • Extra cushioning in the heel, toe and the arch.
  • Quarter height is just above your boot line.
  • Increased durability in high-abrasion areas.

Just Right

Been wearing FITS socks for several years. Wasn't sure about the collar on this one. It actually keeps the sock above the ankle and isn't too tight or cumbersome. The sock is not hot in the Arizona super heat that we had this year.

Well made and functional!

I love the fits company and socks. You always get what you expect . They fit well, wash well and last a long time.



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.
