Hot or cold

I wear these light rugged hikers year round, hot weather or cold. No sweaty feet or funky toe jam. I’ve worn these exclusively for the past two years.

Hardy Sock

Of the socks I have purchased from fits, the Rugged socks are true to their name. With or without shoes, these socks preform well in all conditions, wicking moisture and maintaining a comfortable foot temperature. Thick enough to keep your foot warm, but not too warm for summer weather.

Warm and Dry

Since transitioning, I've noticed my feet are always sweaty. Do all men always have sweaty feet? All my friends say yes, and i feel like someone should have warned me, so here's me warning you, in case you or someone you love is about to start taking testosterone - you are about to form sock opinions, and you are about to go through multiple pairs in a day. I had these sent to me as replacements after mailing back my raggedy old pair. The last pair was a lighter kind of sock, but the guy replacing them suggested i try these instead based on the wear they took and it was definately the right call. ive been wearing the three pairs i got basically exclusively ever since, often taking them off when im home to dry off and popping on another, for a month or two and theres still no wear at all. theyre comfortable and warm but not too warm and serve me equally well in shoes or around the house. big fan, thank you

Sock Sizing
women and men size chart

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.
