Great Cycling Socks

These socks are sold as running socks, but they are better than most socks sold for cycling!

Best socks for. Tennis- ever!

I have tried more than 8 name brands of socks. And non compare to FITS. They were recommended by a tennis partner— and it is the only dock I will ever wear!

Excellent in hot climates. High enough to keep desert flora and fauna away. Brighter colors would be great

Waiting for cooler weather

This has become my go-to sock when the temperatures begin to dip a little. Living in the SW part of the US, I look forward to the Fall and the dropping temperatures. It's my favorite time of year when you need a lighter jacket in the morning and pants all day. When I do, I make sure I have plenty of your Micro Light Quarter socks on hand. They cover just enough for keeping your legs warm, and they provide great support for you feet. With June just about done, I'm one month closer to my favorite time of the the year. Bring on the Fall!!

Running Sock

I instantly felt comfortable running in the micro light runner. I always used a much thinner sock as these are thicker but don't feel like a thick sock when running. I will definitely purchase more of these.

Great sock

I love this sock. It doesn't feel hot and keeps my feet from getting sweaty. I hope FITS makes them in some additional colors.

Sock Sizing

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.
