Extra-Firm Graduated Compression
Designed to provide stronger pressure at the ankle and gradually reduce pressure upward.
30 to 40 mmHg is extra-firm compression. Thigh-high coverage extends support above the calf, which may matter when swelling, vein symptoms, or provider recommendations involve more of the leg.
Because this style covers more area and uses stronger compression, proper sizing matters. A thigh-high stocking that is too tight can feel uncomfortable at the top band. A stocking that is too loose may slide or fail to provide the intended support.
Designed to provide stronger pressure at the ankle and gradually reduce pressure upward.
Extends support above the knee for users who need more than calf-level compression.
Often chosen when lower compression levels or knee-high styles are not enough.
Built for dependable graduated pressure and daily support.
Thigh-high compression requires accurate ankle, calf, thigh, and length measurements.
Best For: Above-the-knee support, extra-firm compression needs

This collection is for people who need extra-firm support beyond the calf. It may also help users whose symptoms extend above the knee or who have been told to use thigh-high compression.

Compression socks are measured in mmHg, or millimeters of mercury. The higher the number, the firmer the compression. Graduated compression means pressure is strongest at the ankle and gradually decreases upward.
| Compression Level | Support Level | Typical Use |
|---|---|---|
| 8 to 15 mmHg | Light |
Mild daily support, light travel, minor fatigue |
| 15 to 20 mmHg | Moderate |
Mild swelling, standing jobs, general support |
| 20 to 30 mmHg | Firm |
Stronger daily support, more noticeable swelling, and varicose veins |
| 30 to 40 mmHg | Extra Firm |
More advanced support needs are often used with provider guidance |
Thigh-high compression requires more measurements than knee-high compression. Do not choose by shoe size alone.
How to Measure
This calculator is a general guide only. Always review the size chart on the product page before ordering.
| Measurement | Where to Measure | Why It Matters |
|---|---|---|
| Ankle | Narrowest point above the ankle bone |
Determines the strongest compression zone |
| Calf | Widest part of the calf |
Helps prevent uneven pressure |
| Thigh | Widest part of the upper leg |
Helps the top band fit without digging or sliding |
| Length | Floor to thigh measurement point |
Helps the stocking sit in the correct place |
More traditional stocking feel and better for cooler environments
Gives the forefoot more room and can feel cooler during longer wear
Best when support needs extend above the calf
Often easier to apply and enough when symptoms stay below the knee
Extra-firm thigh-high compression takes patience to apply. Put the stocking on before swelling builds during the day.

It may be. This is extra-firm compression and covers more of the leg than knee-high styles. If you are new to compression or unsure about this level, consult your healthcare provider.
Choose thigh-high when symptoms extend above the calf, when your provider recommends upper-leg support, or when knee-high compression does not cover the area you need supported.
30 to 40 mmHg is often associated with provider-guided use. Consult your healthcare provider before choosing this level if you are unsure.
Choose open-toe if you want more forefoot room or a cooler feel. Choose closed-toe if you prefer a traditional stocking feel.
Wear time depends on your symptoms, fit, comfort, and healthcare provider guidance. Many users wear compression during the day and remove it before sleep unless told otherwise.
