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 weave, suit-grade performance Merino wool.
Our custom blend of man-made fibers selected for the best breathability and fit.
Love these! Great for lite hiking and every day use. My feet never sweat in these! Definitely going to get a couple more pairs.
Love this style!!
I am extremely happy with all of the FITS socks. All very comfortable and warm.
I love this design, the design and comfort is to be expected, but the fun color and dots add a pop
Great socks––comfortable, cushioned and warm.
I love Fits socks. They are the most comfortable, durable socks out there. They also stay in place & come in great colors & styles. The performance trail socks are my favorite to walk & bike in!!
Thickness of foot is thinner than I wanted.
These trail socks are great! I like the height. This height keeps dirt, stickers, small rocks and anything else out of the socks. I wear mine for hiking, biking, and everyday wear!
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.
