    These socks might be the most comfy I’ve ever owned

    The quality is above anything I’ve purchased from REI Or Duluth trading or and hiking store here in Michigan. I’ve worn this brand now for almost 3 years. The sock last forever and are so soft!

    Not true boot socks

    These are crew socks that can be worn with hiking boots. Came here from Google from the title boot socks but boot socks are taller than crew. That's what I would have bought.

    Hello Cade, Thanks for the review! I'm sorry you aren't happy with these socks. FITS Crew height comes up to the calf and our Boot height is a mid-calf style. This may vary slightly based on body type but if you are wearing the correct size, the Boot height will come up to mid-calf. If you have any questions, please reach out to customer service at help@fitssock.com. Thanks!

    Great sock!

    I purchased these specifically to wear under my tall muck boots when the weather is cold-between the warmth and the cushion, they really do the job.

    Warm and snug

    These fit perfectly around my feet and ankles with no air spaces. And they are thicker than my regular wool socks, so my boots are warmer. They're expensive but worth the money.

    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.
