Compression, explained

What does mmHg mean?

It’s how firmly compression hugs your leg. The higher the number, the firmer the hug.

30–40 mmHg Extra firm

Our firmest hold, for people who want maximum support.

Our socks & sleeves at this level

mmHg stands for millimeters of mercury, the same unit used to measure blood pressure.

  1. Lightest below the kneeGentle pressure where the sock ends.
  2. Easing through the calfThe squeeze steps down as the leg widens.
  3. Firmest at the ankleThe strongest hug sits lowest.
Graduated compression: firmest at the ankle, lighter toward the knee.

If you have a medical condition, ask your doctor which compression level is right for you.

Easier than it looks

How to put on compression socks.

Firm socks take a little technique. Here’s the easy way.

  1. 1. Grab the heel.

    Reach inside the sock, pinch the heel and turn the sock inside out down to that point.

  2. 2. Step into the foot.

    Slide your foot in and line up your heel with the heel of the sock.

  3. 3. Roll, don’t pull.

    Gently unroll the sock over your ankle and up your calf, a little at a time.

  4. 4. Smooth it out.

    Smooth any wrinkles. The top band should sit just below the bend of your knee.

Frequently asked questions

Which compression level should I choose?

20–30 mmHg is firm, a popular choice for workouts and long days. 30–40 mmHg is extra firm, for people who want maximum support. If you have a medical condition, ask your doctor which level is right for you.

What’s different about Wide Calf?

Wide Calf socks have more room through the calf, with 30–40 mmHg compression, in sizes M to 2XL.

How do I find my size?

Socks fit by your calf and shoe size. Use “Find my size” on this page, and choose the size you measure rather than sizing up.

Where should the top of the sock sit?

Just below the bend of your knee, lying flat without folding over.

How do I wash them?

Machine wash cold and hang dry. Skip fabric softener and the dryer so they keep their compression.

What if they don’t fit?

You have 30 days to return or exchange. If you just need a different size, we’ll ship the replacement at no extra shipping cost.

How to put on Compression Socks

1. Put your hand inside the sock, grab onto the toe box and pull the sock inside out all the way to your hand.
2. You're going to put your foot in until your toes touch the front of the sock, and then peel it back over your heel.
3. Pull the sock up onto your leg. 

And that's how you put on a pair of compression socks.
