The 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. Similar to the Light Performance trail but designed in a medium weight for colder weather.
All our socks are made with 18.5m superfine knit, suit-grade performance Merino wool.
Our custom blend of man-made fibers selected for the best breathability and fit.
Great look - great feel
I found a pair of FITS socks at a thrift shop years ago. I marveled at how they conformed to my feet and provided a toasty experience for me at home. Usually I have to double socks in my house. Not necessary when I wear FITS Performance Trail socks. I finally found the same socks on the FITS website years later. I am thrilled and hooked for life!
We’ll made, properly thick, perfect, snug fit.
Love these socks and wish they were in other feminine colors.
These socks are very comfortable and have performed well in outdoor activities including running, biking and hiking. I have had some durability issues in the past but these are holding up well.
The Performance Trail-Quarter is a great in-between sock and very versatile. It can be worn with either shoes or boots. I wear the sock with shorts, but it also works with pants. Great travel sock that covers all the bases!
For the last few years these have been my biking sock choice. Alway soft and comfortable!
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.
