Can you wear wool socks everyday?

Yes! Many people hear “wool socks” and think of those thick winter socks you’d wear under your ski boots. But wool socks are much more versatile than you might think. FITS® merino wool socks for women come in different lengths and thicknesses so you can comfortably wear them as part of your everyday attire. 


Merino wool is one of the best materials for socks and therefore, for your feet! Merino wool is naturally antimicrobial, helping to prevent foot odor that often plagues synthetic socks. It’s also breathable, quick-drying and wicks moisture away from your skin. 


And while your merino wool socks might have a higher price tag, it’s important to remember that wool fibers are designed to last and last. You expect your cheap 12-pack of cotton socks to wear down with every wash because cotton fibers are not very strong. Wool fibers on the other hand are thick, durable, and hold their original shape even when used as your everyday sock. 


What are the benefits of wearing wool socks?

Wool is consistently ranked as one of the best sock materials - and for good reason. Besides being one of the softest natural fibers, merino wool offers a host of other benefits. 


Merino wool socks are naturally antimicrobial, meaning they help to inhibit the growth of microorganisms that can lead to odor and other unpleasant foot issues. Think about it - sheep would have a hard time if their dense wool coats weren’t working for them! 


In addition to antimicrobial properties, wool socks are moisture-wicking and quick-drying. Rather than trapping moisture between the sock and your foot, it wicks it away and quickly dries, leaving your feet feeling comfortable all day. 


Because wool fibers are incredibly durable, you can expect your merino wool socks to last a long time. Wool fibers are strong and not prone to shedding or breaking like cotton fibers, and won’t lose their shape like some synthetic socks. 


The list goes on! From breathability to durability, wool socks are the way to go.


What type of socks are best for walking?

When choosing the best socks for walking, there are a few qualities that you want to look for: breathability, durability, cushioning, and comfort are just a few. 


Wool consistently outperforms other materials at all of the above! 


Wool socks are naturally antimicrobial and wick away moisture, allowing more breathability than synthetic socks. Unlike cotton which retains moisture, wool dries quickly so your feet can feel fresh even on long walks. 


Merino wool socks are also incredibly durable. Wool is a strong, sturdy fiber that doesn’t break down or lose its shape quickly like cotton or synthetic materials. That means that your wool socks will last much longer than a cheap pack of cotton socks. 


For walking socks, you want to consider how much cushion is on high-impact points like your heel and toe. While most socks have a heel and toe thickness of 18.5 microns, our merino wool socks offer 23.5 microns of thickness. 


Finally, comfortable socks are vital for walking long distances. The last thing you want is to find yourself halfway through your walk with a blister forming. Because merino wool wicks moisture from the skin, the chances of blisters forming is significantly reduced when compared to other materials.



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.
