Recently acquired several pairs of ultra light and micro light runners to add to my collection of FITS socks. Best mix of style, comfort, warmth and durability at this price point with no close second IMO and these are no exception. Also love that they are USA made. You can go to REI or Dick's and spend more to get less or you can buy FITS. No brainer. andy
United StatesI have relatively small feet (Women's size 5 1/2) and have really had problems with "one size fits all" socks bunching up and causing calluses and/ or blisters. I walk and work out at the gym a lot so this is a real issue for me. The Fits socks actually do fit, so I don't have those problems any more. The only negative comment I can make is that they do pill quite a bit.
United StatesI love Fits ultralight running no show socks. They have plenty of padding without being too thick. I love the material. It absorbs wetness quickly and dries quickly when you take your shoes off. It does not slip down at all. I have gotten rid of all my other running, exercise socks. These are the best!
United StatesI’ve been wearing these socks for 10 years or so. The only socks I wear, with the exception of the Fits compression and boot socks (OTC) every so often. Well made, soft and last a long time. That’s why I keep coming back to them.
United StatesThe dark heel and ball of foot areas may minimize the visibility of any discoloration from use. The ultra light fabric weight and height may help with heat dissipation while exercising. I prefer to have some feel for the ground.
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.
