Becoming One in Seven Billion With Craig Fowler - FITS®

August 26, 2019

There aren’t many people who can say they were the first in history to do something amazing — but Craig Fowler can.

There also aren’t many people who can say they are the only person in history to do something amazing — but Craig Fowler can.

In 2017, Fowler became the first (and still only) person to complete both the thru-hiking and bikepacking Triple Crowns. If you’re not familiar with these two ambitious challenges, they include thru-hiking the Appalachian Trail, the Pacific Crest Trail and the Continental Divide Trail, as well as bikepacking the Tour Divide, the Colorado Trail and the Amazon Trail. In total, this challenge consists of more than 11,600 miles of hiking and biking.

“For me, I love the planning aspect of these adventures and I love doing it,” he says. “The lifestyle of hiking or bikepacking like that is almost like living life in one of its simplest forms.”

Fowler was inspired to complete the double Triple Crown after watching the movie The Martian, which led him to consider what he could do that no one else in the world had ever done — making him the only one out of seven billion people to achieve something. With both the Appalachian Trail and the Pacific Crest Trail already under his belt, the idea for the challenge was born.

Dubbed the One of Seven Project, Fowler now hopes to inspire others to find their passions and chase down their goals. “It’s not to inspire people to do what I did necessarily,” he says. “The goal is more to just encourage people to know themselves and their passions. It’s one thing to know who they are, but people let life get in the way.”

And just because he’s completed his challenge doesn’t mean Fowler is done chasing down big passions. While he coyly alludes to “another crazy idea” that he isn’t ready to share just yet, he’s still an avid hiker who has devoted his life to seeking out adventures. Up next: the John Muir Trail, which is 211 miles in the heart of the Sierras. Fowler completed portions of the trail during his Pacific Crest Trail thru-hike in 2007 and calls it, “the cream of the crop.”

“The PCT is my favorite,” he says. “It’s the remoteness of the Sierras — there’s no road for 200 miles — and the views. I love that granite and the sparse pine trees out there.”

Throughout his hiking and bikepacking journey, Fowler has naturally tried out a lot of gear. “It’s one of those things where you find something you like and it works well, so you don’t change it. That’s FITS socks for me,” he says. “My oldest pair is a couple of years old and they’re holding up really well.”

For his upcoming hike on the John Muir Trail, Fowlers says he’ll be packing several pairs of FITS socks to get him through. Good luck, Craig! We can’t wait to see what you do next.

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.
