Perfect Winter Golf Socks

These socks are perfect for California Winter Golf. They fit my narrow feet, stay up, wash well and keep my feet warm, but not too warm.

Excellent Socks!

As an avid backpacker/hiker who trains 6 days a week, socks are very important to me. These socks are excellent! They are lightweight, moisture-wicking, comfortable and attractive! I like the extra cushioning in the heel. FITS socks are my favorite socks! They just work perfectly for my fitness needs!

Comfy but on the thin side

Great sock, but too thin for my hikers. (I was surprised as I've been wearing FITS exclusively for over 10 years). Also, minor quibble: the socks appear to be a beautiful shade of purple. But when you put them on, and the fabric stretches (as it is supposed to), the "undercolor"--which is white--shows heavily. They may as well not be purple.

Great "grip," but thinner than I expected

I've been wearing FITS hikers for over a decade, and they are my favorite sock, both for hiking and to help relieve nighttime neuropathy. But my latest order is much thinner than my previous pairs. They work fine at night (because the pressure is still good), but they are too thin to wear with my hiking boots.

My favorite socks!

My first pair was a desperate purchase on a ski day to give myself another layer in bad rental boots, and when I found them in my closet again a year later they became my favorite socks so I ordered 2 more! Perfect cushion, great at wicking, really warm.


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.
