For all over-the-calf (knee-high) socks and calf sleeves, your sock size is based primarily on your calf circumference at its widest point. Use shoe size as a secondary reference point.

If you are between sizes, we recommend you size up unless you want a tighter fit, in which case, you should size down.

For all below-the-calf socks, your shoe size is the primary determinant of size.

For your convenience, you can find size charts for all socks here.

IMPORTANT: If you have any doubts about sizing, please email us and we'll help you select the right size.

We do offer wide-calf compression socks and calf sleeves. Both styles are designed to fit calves between 20”-24”. You can view them here. 

Graduated compression socks exert the greatest degree of compression at the ankle and the level of compression gradually decreases up the socks. This forces the blood to move upwards, where there is more space. Visit our compression technology page to learn more about graduated compression.

Compression socks increase blood circulation which helps to rebuild broken down soft tissue. There are many benefits to wearing compression socks, including:

• Reducing swelling, muscle aches and soreness in the legs and feet
• Helps you feel more energized
• Reduces your overall recovery time after exercise or being up on your feet for extended periods of time

Compression socks can help you perform better, whether you're out training or at work, and can help improve your recovery at the end of the day. This article gives a great in-depth explanation of all the benefits of wearing compression socks.

Compression socks are designed to fit tighter than your average sock. They can be challenging to get on, but we have a video on how to best care for your PRO Compression socks and sleeves. 

IMPORTANT: Pulling on your socks too forcefully can damage the socks. Please follow the instructions.

Note: All of our socks have an underlying base compression thread in either black or white coloring. This material will become more visible as the sock is stretched and this is normal. 

We recommend washing in cold water and leaving the socks or sleeves out to air dry.

We do not recommend warm/hot water or putting them in the dryer as this may cause shrinking and degrade the compressive quality of the garment.

Here is a short instructional video on how to best care for your PRO Compression socks and sleeves.

Our socks are built to last for several years if properly cared for. However, if you are hard on your socks via repeated uses and wash/dry cycles, it's possible that they will begin to lose some compression over time.

To ensure optimal performance and compression, we recommend that you replace your socks at least once a year if you are a frequent user of the socks.

Variations from sock to sock are normal and are due to a number of factors. Read on for an explanation, but rest assured this is normal and does not in any way compromise the integrity or performance of your socks.

Socks that are the same size may appear to be different in length when compared side by side. This is due to differences in thread patterns, color of thread used, or thread direction. What is important is that when worn, the socks will fit as intended.

Another difference is that some socks may 'feel tighter' than others. This again is due to the same thread variations listed above. Socks are tested and certified to be within stated compression ranges.

In both instances, after washing and wearing several times, our socks generally start to settle into their final shape, fit and feel.

Some of our newer styles have their designs printed rather than sewn in which results in a different texture and fit when initially handled and worn. Again, washing and wearing will help break them in and they will begin to feel like all of our other socks. NOTE: Socks made via this innovative new printing method have it stated in their respective product descriptions.

All of our products are designed in California. Most of our products are made in the USA and all orders are shipped by American workers.

Due increased global supply chain issues for raw materials, we have begun limited manufacturing in China and Taiwan.

All products, regardless of where they are made, must pass our rigorous quality and testing standards.

The majority of our compression socks and sleeves, including the Marathon line, are made from proprietary blends of nylon, polyester, and spandex.

• Lifestyle socks are blend of cotton, acrylic, nylon, and spandex. Where noted, some styles contain REPREVE®, a yarn made from recycled water bottles and plastics.
• Dress socks are a blend of premium combed cotton, nylon, and spandex.
