FITS® X Free Fly Performance Sock - Limited Release | FITS®

October 22, 2019

If we asked you to name a Charleston-based company that was committed to comfort, made with the highest quality materials and designed to help you enjoy the outdoors with ease…you’d probably think we were talking about ourselves, right? 

And while all of the above is true for FITS, it’s also true for our friends at Free Fly

That’s why it came as no surprise that when our managing partner Matt Alexander met Free Fly co-founder Tanner Sutton, they became almost instant friends.

“I didn’t own any Free Fly apparel at that time and he didn’t own any FITS socks,” Matt says. “I may have even brought socks to the meeting.” 

However, it didn’t take long for the two brands to develop a strong mutual admiration. After swapping gear, the FITS team became big fans of Free Fly — and vice versa.

“They have been really intentional and thoughtful about their product line,” Matt says. “They use great material and it’s a great fit.”

One thing FITS and Free Fly don’t have in common? Socks. Well, until now, at least.

This fall, FITS and Free Fly are teaming up on a collaborative sock launch. For a limited time, Free Fly will sell a FITS Light Hiker Crew, designed with signature Free Fly colors. Fans of each brand can experience the best in Charleston outdoor comfort and quality, while supporting two local businesses.

Head on over to Free Fly to check out the official FITS X Free Fly sock. But don’t wait — supplies are limited and you won’t want to miss out on this special sock.


Sock Sizing

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.)

How Do You Determine Sock Size?

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. 

How Do You Measure Your Foot for Socks?

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. 

What Is the Sock Size Conversion?

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. 

What is Sock Size to Shoe Size?

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. 

What Age is Sock Size 9-12?

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.
