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.

They are the perfect socks! They don't move and keep your feet at the right temperature! No sweating! Just the right amount of cushion!
I was given my first pair as a Christmas gift. I've been preparing for the 20 mile MammothMarch and regular socks gave me blisters after 10 miles. My first trip out in the Fits Performance Trail socks, I logged 13.3 miles and my feet held up great. Then, the night before a scheduled 13 mile hike, I developed a sore on the bottom of my foot and every step was agony. I did not think I'd complete the trail but decided to give it a try. I ended up walking 14 miles that day! The socks and my hiking shoes made all the difference in the world.
This socks fit perfectl and don't move or rub and keep my feet warm! I don't want to wear anything else anymore now! Well made of high quality materials. The quarter socks style is my favorite
I love all the Fits socks, they gently hug your foot all day long and are so comfortable. Highly recommend!
I have never been disappointed with any of the socks I have purchased from Fits. The Performances Trail are so comfortable thinking of buying a second pair.
I continue to purchase FITS Socks They truly do fit
Perfect sock height! Crew socks bunch above boot and below calf. If you have calves these fall just Below calf muscle and above standard hiking boots even taller mountaineering boots. Like I said Perfect sock height imo.
Best Cycling Socks in Heat or in the Cold I've ever had.....now I need more pairs!
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.)
Sock sizes are typically measured in inches, not by your shoe size. So, a sock size 6-8 will comfortably fit someone whose feet are between six and eight inches long. However, at FITS®, we make it easy for you to choose the ideal sock size without having to measure your foot. Simply use our sock size conversion chart based on your shoe size to select the right fit for you.
To measure your foot for socks, measure the length from the heel of your foot to the tip of your longest toe. The measurement in inches correlates to your sock size. For example, if your foot is 10 inches long, a sock size 9-11 should fit you comfortably. At FITS®, you can skip this step and find your sock size based on your shoe size using our conversion chart.
The sock size conversion refers to sock size compared to shoe size. While all companies may vary slightly on which size socks to purchase based on your shoe size, you can always measure your foot to find the right fit for you.
Because sock sizes are determined by the length of your foot in inches vs. your shoe size, shoe and sock sizes differ. The FITS® sock size to shoe size conversion is as follows:
Knowing this makes it easy to choose the ideal sock size based on your shoe size without measuring your foot.
Sock sizes typically don’t correlate with age. For kids, age can be a general indicator of what size sock they’ll need, but everyone is different. An adult sock size 9-12 fits anyone whose feet are approximately nine to twelve inches long. For kids’ sock sizing, check with the company to find exact details to ensure your little one gets the perfect fit.
