    just great socks

    Excellent experience shopping at FITS! I wish FITS socks were available here in Canada. While they are definitely worth the $ exchange rate it always comes as a bit of a shock on the VISA bill! Still, worth it.

    Love Fits socks!

    These are by far the most comfortable, toasty socks I've ever warn. Also, I wear them constantly in the Syracuse Winter and they are wearing wonderfully. I bought my first pair 4 years ago and they are still lasting beautifully, no holes, and I'm hard on my clothes.

    Patriot Guard Rider - Motorcycling

    I bought the FIT Light Ski Socks for summer motorcycling...yes, i said summer. They are amazing at keeping my feet regulated, dry and comfortable inside my riding boots even in triple-digit weather while covering hundreds and even over 1100 miles in a day. I have even worn them multiple days without washing (yuck, I know) but these socks manage that very well with the same level of comfort. I am in the process of buying more for everyday use!

    Best knee socks ever!

    I love these socks. I purchased both the Light Ski and the Ultra Light Ski, and they are both great. I wear the Light Ski with my hiking boots, and the Ultra Light Ski with my very snug mountain bike shoes. Both are super-comfortable and supportive, without being too tight. After reading the reviews, I was a little concerned about how tall these socks actually were - I have a pretty long and slim calf and need a sock to come right up to my knee, and stay there. Both the Light and Ultra Light Ski are plenty tall, and They Do Not Fall Down. I wear size 9 (US) women's shoes and boots, and the ladies' large fits perfectly. Love the colors and patterns, too!!

    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.
