Graduated Pressure
Firmest at the ankle, easing up the leg, to encourage fluid and blood flow back toward the heart.
Graduated Support to Help Move Fluid and Reduce Swelling
Best Medical Compression Socks for Edema
Edema happens when fluid pools in the tissue under your skin, most often in the feet, ankles, and lower legs after a long day of sitting or standing. Rescue Legs makes graduated compression socks that apply the most pressure at the ankle and gradually ease up the leg, paired with real fit guidance so you land on the right size and level the first time. Sizing is based on your actual measurements, not a generic small, medium, or large guess.
How Graduated Compression Helps With Edema
How Graduated Compression Helps With Edema
Edema is fluid that has settled into the soft tissue of your lower legs, usually because gravity and a long stretch of standing or sitting have outpaced your body's ability to move that fluid back up toward the heart. A sock that squeezes evenly, or barely at all, does little to help that fluid move in the right direction.
Graduated compression works differently. It applies the firmest pressure at the ankle and gradually loosens as it moves up the calf, which pushes fluid upward through the veins instead of letting it settle. That pressure gradient is the entire point of a medical-grade compression sock, and it is why fit and pressure accuracy matter more here than with an ordinary sock.

Who It's For
Who Reaches for Compression to Manage Edema?
Not every kind of swelling calls for the same approach, so it helps to see where you fit before choosing a level.
| Situation or Symptom | Compression Level to Consider | What to Look For |
|---|---|---|
| Mild ankle and foot puffiness after standing all day | 15 to 20 mmHg |
Light, breathable support you can wear daily |
| Swelling from long flights or car rides | 15 to 20 mmHg |
Knee-high length, easy to travel in |
| Pregnancy-related swelling in the feet and ankles | 15 to 20 mmHg (with provider approval) |
Comfortable, non-restrictive knit |
| Moderate swelling that persists into the evening | 20 to 30 mmHg |
Reinforced knee-high or open toe if toes are affected |
| Swelling paired with a fuller calf shape | 20 to 30 mmHg, Wide Calf |
A wider calf panel so the sock doesn't roll or dig in |
| Edema tied to a diagnosed condition (venous insufficiency, lymphedema, heart or kidney disease) | Provider-directed, often 30 to 40 mmHg |
Guidance from your doctor on level, length, and daily wear time |
Compression Levels Explained
Understanding Compression Levels for Edema
Compression is measured in mmHg, and higher numbers mean firmer pressure. Here is how each level tends to line up with edema specifically.
| Compression Level | Category | Common Use for Edema |
|---|---|---|
| 8 to 15 mmHg | Light |
Very mild, occasional puffiness with no diagnosed condition |
| 15 to 20 mmHg | Moderate |
Everyday swelling from standing, travel, or mild fluid retention |
| 20 to 30 mmHg | Firm |
Persistent daily swelling or edema that returns each afternoon |
| 30 to 40 mmHg | Extra Firm |
Significant or medically diagnosed edema, typically provider-directed |
Sizing & Fit Tips
Get the Right Fit Before You Order
Compression only works as intended when the size matches your leg, and that starts with a few quick measurements.
How to Measure
1
Measure first thing in the morning, before swelling has built up for the day.
2
Measure around the narrowest part of your ankle.
3
Measure around the widest part of your calf.
4
Measure the length from the floor to just below your knee.
5
If you're considering a thigh-high, measure the widest part of your thigh as well.
Quick Size Calculator
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 |
Sets the base pressure point where compression is firmest |
| Calf | Widest point of the calf |
Determines the pressure gradient as the sock moves up the leg |
| Length | Floor to just below the knee (or to the thigh for thigh-highs) |
Keeps the sock from bunching, rolling, or cutting off at the wrong spot |
| Thigh (if applicable) | Widest point of the thigh |
Needed for an accurate thigh-high fit |
Wearing Guide
Wearing Compression for Edema
Getting the timing right matters almost as much as getting the size right.
-
Morning: Put socks on before swelling has a chance to build up, ideally right after waking up
-
During the day: Keep them on through standing, sitting, or travel, the times swelling tends to worsen
-
Evening: Remove before bed unless your provider has directed otherwise
-
Ongoing: Rotate between 2 to 3 pairs so you always have a clean, elastic pair ready

Care & Maintenance
Care Instructions
Washing
Machine wash per the care label using a mild detergent.
Drying
Carolon products can be machine dried following the approved care guidance.
Storage
Smooth the fabric flat after washing to help the sock keep its shape. Keep 2 to 3 pairs in rotation so compression stays consistent while one pair is in the wash.
FAQ
FAQs
Does compression cure edema?
No. Compression socks help manage swelling and support circulation, but they don't treat whatever is causing the fluid to build up in the first place. If your edema is tied to an underlying condition, that condition still needs its own treatment plan from a provider.
Which compression level should I choose for edema?
Most everyday swelling starts at 15 to 20 mmHg or 20 to 30 mmHg, depending on how persistent it is. Firmer levels like 30 to 40 mmHg are usually reserved for diagnosed conditions and should be worn under a provider's direction.
How long can I wear compression socks each day?
Many people wear them for most of their waking hours, putting them on in the morning and removing them before bed. Your provider may recommend a different schedule depending on your specific situation, so it's worth checking if you have a diagnosed condition.
What if I have a wide or fuller calf?
Our wide calf compression stockings use a wider calf panel while keeping the same graduated compression profile, so the sock doesn't roll down or dig in at the top.
Do I need a prescription for compression socks?
No prescription is required for the compression levels we carry. That said, if you have a diagnosed condition or your doctor has recommended a specific mmHg level, it's worth following their guidance on which level and length to choose.
When should I see a doctor about edema instead of just wearing compression?
See a provider if swelling is new, sudden, one-sided, or painful, or if it comes with shortness of breath, chest pain, or skin discoloration. Those can be signs of a blood clot or a heart, kidney, or liver issue that compression alone won't address.
