    Buy them!

    Best socks I have ever owned. I now have heard how great the no show socks are for running and I plan on getting them as well.

    Great sock

    I purchased fits socks because my Physical Therapist recommended them! They feel great, wear great (at least 3 to 4 years) and are worth the money! I recommend them to my friends!

    Possibly the most comfortable sock I’ve tried

    I stand a lot during my day and have tried a lot of socks. These and the Jon sock are at the top of the list. Sizing may be a little generous. I’m near the bottom of the mens XL range, but am finding I prefer L.

    I use these for cycling and hiking

    I use these for cycling and hiking. They wash well and dry overnight. They give me enough support and cushion to wear biking sandals for 70 hour rides. I can wear them for three days without them smelling. Price is high but they last for two years. Definitely worth the money. I always buy 5 to 7 at a time of the same sock so if they get separated I can make them.

    Best work sock ever!

    19 years ago I purchased several pairs of the Fits socks. This was when they sold only one type of sock. Now they sell a sock for every reason and season. I retired from working at an aluminum smelter/ingot plant and those socks are just as good and comfortable as they were new. I decided to buy some for my son-in-law who wears work boots 12 to 16 hours a day and after speaking to customer service I found out that the original sock they had started out with was now known as the Medium Hiker. He loves them as much as I do. Fits socks will be the last sock you will have to buy in your lifetime!

    feet hugs

    I adore these socks and like to buy them for my friends so their feet can be hugged as well. They actually sent me the wrong size for my buddy, but happened to be my size, so I guess I get a new pair! They are good looking and feel amazing. If you buy them to ski, then extra bonus points

    Best socks ever!

    These truly are the most comfortable socks I have ever worn. They hug your foot and never seem to lose ther shape and don't slide around in your shoe.



    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.
