United StatesFITS are so aptly named - they are feet-fitting, with no extra fabric to bunch up or abrade. I have 3 pair & rotate them to wear daily fall through spring. Perfection!
THIN LINERS AND THICK HIKERS ARE THE WAY TO GO. THEY ARE PRICEY. THESE SOCKS DO THE JOB. I HOPE THEY GET SOFTER WITH WASHING, AS THEY SEEMED A LITTLE ROUGH THE FIRST TIME WORN. THEY ARE A VERY CLOSE FIT, STILL STRETCHY.
I switched from SmartWool to Fits several years ago when the store I usually bought the SW’s from was out and recommended the Fits. I felt the difference as soon as I put them on. The name is appropriate because the fit is incredible. The medium crew hiker is luxuriously soft, yet wears like iron. I wear them every day from Fall to Spring here in Michigan and get several years out of them. I would be lucky if a pair SW’s lasted through one. I recently discovered the Heavy Expedition boot sock and just ordered 4 more pair! I also love the fact that they are made here in the USA and that they offer Active Duty, Vets and First Responders a substantial discount. Thank you, Fits, for the most comfortable, supportive, durable, and just plain best socks I have ever owned!
Thanks for the kind comments! We are very glad you like your FITS!
Great socks. They stay put. No slidding down. All day comfort. The best sock ever!
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.)
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.
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.
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.
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.
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.
