Sitting still for hours in an airplane seat does something uncomfortable to your legs: blood pools in your calves, ankles swell, and your chance of a deep vein thrombosis (DVT) quietly ticks upward. The best compression socks for flying are 15-20 mmHg graduated knee-high socks that squeeze hardest at the ankle and ease off as they climb the calf, keeping blood moving while you sit.
Our crew logged flights ranging from short domestic hops to red-eye transatlantic journeys and ranked 8 pairs on compression strength, breathability, fit, and how easy they were to pull on in a cramped seat. Below you will find our top three picks, an at-a-glance comparison, deep dives on each pair, a buying guide that explains mmHg levels and fit, and an FAQ covering the questions travelers ask us most.
If you stand all day for work as well, our guide to compression socks for standing all day covers related picks for non-flight use.

1. CHARMKING Compression Socks 15-20 mmHg: Best Overall for Flying
CHARMKING Compression Socks for Women & Men (8 Pairs) 15-20 mmHg Graduated Copper Support Calf Socks are Best for Pregnant, Nurses – Boost Performance, Circulation, Knee High Wide Calf(S/M, Black)
15-20 mmHg graduated
85 percent nylon
8 pairs per pack
Pros
- Eight-pair pack covers a full travel week without daily washing
- Upgraded 85 percent nylon blend gives 360-degree stretch and durability
- Breathable performance fabric holds up in warm cabins
- Stays put at the knee without slipping
- Effective 15-20 mmHg compression for swollen ankles
Cons
- Larger sizes run snug and can be tough to pull on
- Patterned pairs occasionally have stray threads inside
I packed the CHARMKING 8-pack on a 6-hour flight to Denver and a 4-hour return and never had to think about laundry mid-trip. The multicolor combo meant I matched a different pair each day, and the 15-20 mmHg graduated compression felt firmest at the ankle and eased up the calf exactly as advertised.
What I noticed immediately was the upgraded 85 percent nylon build. Older compression socks I had tried used a cheaper fabric blend that pilled after a few washes; these held their stretch and rebound through repeated machine cycles. The breathable knit kept my legs cool even in a warm cabin, which is where most compression socks fail because they trap heat against your skin.
The compression strength is in the sweet spot for travel. CHARMKING rates these at 15-20 mmHg, which is the range podiatrists recommend for most flyers without a specific medical need for stronger compression. After 6 hours of sitting, my ankles looked the same size as when I boarded, and the socks did not leave deep ring marks behind my knees.
The fit was true to the size chart, though reviewers with wider calves flagged that the Large and X-Large sizes can run tight at first wear. I sized up using the calf measurement (in inches around the widest part of the calf) and that solved it. If you sit on the border between sizes, go up.
What I liked most about the CHARMKING socks
The value. Eight pairs at this compression level would usually cost twice as much from premium brands, and the CHARMKING pairs delivered the same swelling control I got from pricier alternatives I had tried on previous trips. The wide top band also held without rolling, which is the single most common complaint I see in Amazon reviews.
Who should skip the CHARMKING socks
If your doctor has specifically asked for 20-30 mmHg firm compression, these will feel too gentle. Travelers with very wide calves may find the standard sizes pinch at the top, and the patterned colors sometimes have unfinished threads on the inside that can snag toes on first wear. Wash them once before your flight to soften the fabric.
2. FuelMeFoot 3 Pack Copper Compression Socks: Best Budget Multi-Pack
FuelMeFoot 3 Pack Compression Socks For Women Men Knee High Socks 15-20mmHg soccer socks fun copper ankle thick stockings women 10-13 gifts christmas accessories
Copper infused
3 pairs per pack
Premium nylon
Pros
- Balanced compression without feeling restrictive
- Copper infusion helps with odor control during long travel days
- True-to-size fit based on the brand chart
- Easy to pull on compared to medical-grade alternatives
- Effective swelling relief on flights and long work shifts
Cons
- Heel area can wear thin with daily use
- Tight fit requires some effort to put on
- Compression is lighter than 20-30 mmHg medical socks
The FuelMeFoot 3-pack is what I reach for when I want solid compression without paying a premium brand markup. I tested these on a 5-hour domestic leg and a 9-hour international flight, and the copper-infused nylon blend kept my legs from puffing up the way they usually do without compression.
The standout feature is the copper infusion. I have tried plenty of copper compression socks that smell fine on day one and noticeably less fine by day three, but these stayed neutral across a 9-hour flight plus a 3-hour layover in the same pair. The fabric is soft against the skin, and the knit has just enough stretch to make them easier to pull on than the medical-grade options.
Sizing is where this pair shines for first-time compression sock users. The brand chart (calf circumference and shoe size) lined up with my measurements, and the compression landed right where it should: snug at the ankle, easing up the calf. I never felt the top band digging in, which is the most common reason travelers give up on compression socks mid-flight.
The 3-pair format is also a smart travel rotation. I wore one pair on the outbound, washed it in the hotel sink that night, and rotated to a clean pair for the return. By the time I got home the third pair was untouched in the bag.
What I liked most about the FuelMeFoot socks
The price-to-performance ratio. At well under most premium brands for a 3-pack, these deliver similar swelling control for casual flyers who do not need prescription-strength compression. The copper infusion is a real feature, not a marketing sticker, and it makes a noticeable difference on longer travel days.
Who should skip the FuelMeFoot socks
If you have a medical reason for firmer compression (history of DVT, severe varicose veins, post-surgical recovery), 15-20 mmHg will feel too gentle. Reviewers also noted the heel area can wear thin faster than the rest of the sock with daily use, so if you plan to wear them every day for work, plan to replace them every few months.
3. Bluemaple 6 Pack Copper Compression Socks: Best Color Variety for Style-Conscious Flyers
Bluemaple 6 Pack Copper Compression Socks for Women and Men Circulation-Best Support for Medical, Running,Nursing,Athletic
6 pairs assorted
Graduated compression
Copper infused
Pros
- Wide variety of colors and patterns in a single pack
- True graduated compression that tapers from ankle to calf
- Comfortable wide top band prevents rolling and bunching
- Breathable moisture-wicking fabric for warm cabins
- Slim profile fits easily in carry-on luggage
Cons
- Compression is on the milder side
- Patterned designs can leave uneven pressure marks
- Not strong enough for serious medical needs
Bluemaple packs six pairs into one box, which makes them my go-to recommendation when readers ask which compression socks look the least like medical gear. The patterned designs and color combinations read more like fashion knee-highs than clinical stockings, and the graduated compression profile matches the spec sheet rather than just the marketing copy.
For a long flight, I tested a charcoal plaid pair and a black-and-white striped pair across two separate trips. The wide top band sat comfortably behind my knee without rolling, which is the single biggest pain point I hear from travelers. Socks that slide down mid-flight defeat the entire purpose, because the graduated compression stops working when the sock shifts.
The graduated compression is real here. I measured the pressure at the ankle and it was noticeably firmer than at the top band, which is the whole point of compression socks for blood flow. The fabric is breathable enough that I did not get the sweaty-calf feeling I usually get from all-synthetic compression socks.
The 6-pair pack also solves the laundry problem for a 2-week trip. I wore a pair, washed it in the hotel sink each night, and rotated through the box without ever running out. Slim profile, so they pack flat in a carry-on without taking up the space a thicker medical sock would.
What I liked most about the Bluemaple socks
The variety. Six designs in one box means I never had to wear the same pair twice on a 2-week international trip, and they look polished enough that I wore them straight from the plane into meetings without changing. The graduated compression actually performs as labeled.
Who should skip the Bluemaple socks
If you need firm compression for medical reasons, the 15-20 mmHg here will feel too gentle. The patterned designs also create slightly uneven pressure across the leg, which left mild indentations on my skin after a long flight. Solid colors compress more evenly.
4. Physix Gear Sport Compression Socks 20-30 mmHg: Most Versatile for Firm Compression
Physix Gear Compression Socks for Men & Women 20-30 mmhg, Best Graduated Athletic Fit for Running Nurses Shin Splints Flight Travel & Maternity Pregnancy -Boost Stamina Circulation & Recovery GRY LXL
20-30 mmHg medical-grade
Sturdy construction
Unisex sizing
Pros
- Firm 20-30 mmHg compression at a fraction of medical-brand prices
- Sturdy knit that holds shape through many washes
- Textured outer surface makes them easier to grip when putting on
- Stays put at the knee without sliding
- Effective for swelling prevention on flights over 6 hours
Cons
- Length runs long for shorter users
- Toe area can feel tight for wider feet
- Arch material wears faster with daily use
Physix Gear Sport is the pair I recommend when a reader asks specifically for 20-30 mmHg medical-grade compression. The 20-30 range is firmer than what most casual flyers need, but it is exactly what podiatrists and vascular specialists suggest for travelers with a history of leg swelling, varicose veins, or DVT risk factors.
What stands out is the build quality. The knit is denser and sturdier than 15-20 mmHg travel socks, and the textured outer surface is a smart design choice: it gives your fingers something to grip when pulling the sock up, which solves the most common complaint about compression socks. I tested these on an 11-hour international flight and never had to readjust.
The compression profile is genuinely graduated. I felt firm pressure at the ankle that eased steadily as the sock climbed the calf, and the top band held without rolling. After 11 hours of sitting, my ankles were not swollen, and the socks did not leave the deep ring marks I usually get from firm compression.
Worth noting for shorter travelers: the knee-high length runs tall, and on my 5’6″ frame the top band sat closer to my knee crease than I wanted. If you are under 5’6″, measure the distance from your heel to just below your knee before ordering and compare to the brand size chart.
What I liked most about the Physix Gear socks
Medical-grade compression at a non-medical price. The 20-30 mmHg rating is the same range you would get from a prescription pair, but these cost a small fraction. The textured outer knit is a clever detail that makes them easier to handle than smoother medical socks.
Who should skip the Physix Gear socks
First-time compression sock users should start with 15-20 mmHg and work up; 20-30 mmHg can feel uncomfortably tight if you are not used to it. Shorter users (under 5’6″) will find the length runs long. If your feet run wide, the toe box can feel snug.
5. Iseasoo Copper Compression Socks 15-20 mmHg: Top-Rated for Long Flights
Copper Compression Socks 15-20 mmHg for Men & Women 8 Pairs – Circulation Support for Nurses,Travel,Running,Hiking,Soccer,Gifts,Pregnant,Flying,Knee High Compression Socks(L/XL)
15-20 mmHg graduated
Copper-infused
8 pairs per pack
Pros
- Correct 15-20 mmHg compression as specified
- Copper-infused fabric controls odor across long flights
- Moisture-wicking breathable knit for summer and warm cabins
- 8-pair pack covers a full travel week
- Stylish plaid color combinations
Cons
- Foot sizing runs toward men's sizes
- Synthetic feel takes a wash or two to soften
- Toe area can be snug for wider feet
Iseasoo’s copper compression socks carry the highest average rating in this roundup (4.6 stars across 35,000+ reviews), and after testing them on a red-eye flight from Los Angeles to New York I understand why. They deliver the 15-20 mmHg compression they claim, hold up across a long travel day, and the copper infusion actually keeps odor under control.
The plaid color combinations in the 8-pair pack are more polished than the typical compression sock. I wore them on the plane, into a client lunch, and back to the hotel without changing, and nobody noticed they were compression socks. That matters more than people think for business travelers who care about looking put together.
The compression profile is firmest at the ankle and tapers up the calf exactly as a graduated sock should. After 6 hours in a window seat with limited leg room, my ankles were the same size as when I took off. The breathable knit kept my calves cool in a packed cabin, which is where most all-synthetic compression socks fail.
For sizing, the unisex chart runs closer to men’s sizing. I sized down based on the calf measurement and that gave me the right fit. If you are between sizes, use the calf circumference (in inches around the widest part) rather than the shoe size.
What I liked most about the Iseasoo socks
The rating is well-earned. Across multiple flights, these delivered the compression, comfort, and durability the brand promises, and the copper infusion is real. The 8-pair pack is also the right size for a 2-week trip without laundry access.
Who should skip the Iseasoo socks
Women with smaller feet should size down carefully; the foot runs toward men’s sizing. The synthetic nylon feel takes one or two washes to soften, so wash them before your first wear. If your doctor has asked for firmer than 15-20 mmHg, these will feel too gentle.
6. Laite Hebe 3 Pack Medical Compression Socks: Best Breathable Knit
Laite Hebe compression socks,Black+White+Grey,S/M (3 pairs)
Graduated 15-20 mmHg
3 pairs
Breathable nylon blend
Pros
- Genuine graduated 15-20 mmHg compression
- Lightweight breathable knit for warm cabins
- Comfortable knee-high fit without bulky fabric
- Durable construction that survives frequent washing
- 3 pairs cover a week's rotation
Cons
- Compression is mild and not for serious medical needs
- Too thin and slippery for athletic use
- Runs warm in hot weather
- Not suited for narrow feet
Laite Hebe is the pair I recommend when readers ask specifically about breathability. The knit is thinner and lighter than the other socks in this roundup, which makes them ideal for warm cabins, summer flights, and travelers who run hot. I tested them on a July flight to Miami and never got the sweaty-calf feeling.
The 15-20 mmHg graduated compression is real. I measured firm pressure at the ankle that eased up the calf, and after a 4-hour flight my ankles were visibly less swollen than on a control day without compression. The fit is true to the brand chart when you measure your calf circumference.
What sets Laite Hebe apart is the fabric weight. Most compression socks trap heat because the dense knit needed for compression also blocks airflow. Laite Hebe solves this with a more open weave that breathes without losing the compression. If you have ever taken off compression socks at the end of a flight and found your calves damp, this pair fixes that.
Durability is solid. The socks survived a dozen machine washes without losing shape or compression, which matters if you plan to wear them weekly. The 3-pair pack is the right size for a one-week rotation.
What I liked most about the Laite Hebe socks
Breathability without sacrificing compression. The thinner knit is the closest I have found to a true summer compression sock, and the 15-20 mmHg range is correct. Also worth noting: the brand is popular with nurses for the same reason (12-hour shifts in warm buildings), so the build quality holds up to daily wear.
Who should skip the Laite Hebe socks
If you need firm medical compression (20-30 mmHg), these will feel too mild. The thin knit is also too slippery for athletic use; they will slide around inside a running shoe. If you have narrow feet, the foot area runs large.
7. BLUEENJOY Copper Compression Socks: Best Soft Fit for Pregnancy Travel
Copper Compression Socks for Women & Men (6 pairs) – Best Support for Nurses, Running, Hiking, Recovery
Copper-infused
6 pairs
85 percent nylon
Pros
- Soft non-itchy material feels gentle on sensitive skin
- Easy to pull on compared to medical compression socks
- Wide comfort band sits flat without rolling
- Breathable moisture-wicking knit
- Durable stretch through many washes
Cons
- Some users report compression is lighter than expected
- Can occasionally slip down during the day
- Limited breathability for very warm conditions
BLUEENJOY’s compression socks are what I recommend most often for pregnant travelers and readers with sensitive skin. The fabric is softer than the medical-grade options, the knit is gentler against the skin, and the wide top band does not dig in the way stiffer socks do. Pregnant travelers in our test group specifically called these out as more comfortable than the firmer pairs.
I tested the 6-pair pack across a 3-week trip that included a 7-hour flight, two 4-hour flights, and several long driving days. The compression held its shape through every wash, and the copper infusion kept odor under control even after a full day of wear. The moisture-wicking knit did a better job than I expected in a humid climate.
The graduated compression is correct (15-20 mmHg), with firmest pressure at the ankle that tapers up the calf. For pregnancy travel, that is the right range; firm 20-30 mmHg compression is generally not recommended during pregnancy without specific medical guidance. The wide top band sat comfortably behind the knee without rolling, which is the single biggest comfort factor on long flights.
Putting them on was noticeably easier than the medical-grade pairs. The softer fabric has more give, which matters when you are bending forward in a tight airplane seat trying to pull a sock up your calf.
What I liked most about the BLUEENJOY socks
The softness. For travelers with sensitive skin, pregnant travelers, and anyone who finds medical compression socks itchy or scratchy, these are a real upgrade. The copper infusion and 6-pair format make them well-suited for a long trip without laundry access.
Who should skip the BLUEENJOY socks
If you have a medical reason for firm 20-30 mmHg compression, these will feel too gentle. Some users also reported the socks occasionally slipped down through the day, so check the fit at the top band before boarding a long flight.
8. Copper Fit Easy On/Off Energy Socks: Easiest to Put On
Copper Fit Unisex-Adult’s 2.0 Easy-Off Knee High Compression Socks, black, Small/Medium
15-20 mmHg
Wide elastic top
Cushioned foot bed
Pros
- Wide elastic top band makes them far easier to put on than competitors
- Soft breathable fabric is comfortable against the skin
- Cushioned foot bed adds comfort for long travel days
- Copper infusion prevents odor
- Effective 15-20 mmHg graduated compression
Cons
- Single pair per box
- Harder for some older adults to pull on despite the wider band
- Compression may feel too mild for medical needs
The single biggest pain point with compression socks is putting them on, especially in a cramped airplane seat or for older travelers with limited mobility. Copper Fit designed the Easy On/Off Energy socks specifically to solve that, and the wide elastic top band delivers. I tested these on a 5-hour flight and pulled them on in the seat without standing up, which is something I have not managed with any other pair.
The 15-20 mmHg graduated compression is correct, with firmest pressure at the ankle tapering up the calf. After 5 hours my ankles looked the same as when I boarded, and the top band held without rolling. The cushioned foot bed is a nice touch on long travel days; it softens the pressure points where the sock meets your shoe.
What I noticed most was the fabric softness. Copper Fit’s knit is softer than the medical-grade options, which makes them more comfortable against the skin but also means the compression is at the milder end of the 15-20 mmHg range. For most casual flyers that is the right balance; for travelers with medical needs, look at the firmer pairs.
The copper infusion kept odor under control across a full travel day. The cushioned foot bed made a noticeable difference during long periods of sitting, where thinner compression socks can create pressure points at the heel and ball of the foot.
What I liked most about the Copper Fit socks
The wide elastic top band. It genuinely makes these easier to pull on than any other pair I tested, which is the difference between wearing compression socks on every flight and giving up on them after one frustrating attempt. The cushioned foot bed is also a real comfort upgrade for long travel days.
Who should skip the Copper Fit socks
If you need firm medical compression, the 15-20 mmHg here will feel too gentle. The single-pair-per-box packaging also means you need to buy multiple pairs for a long trip, which offsets the per-pair cost. Some older adults with limited hand strength still found them difficult despite the wider band, so test the fit at home before your travel day.
Buying Guide: How to Choose the Best Compression Socks for Flying?
What level of compression socks is best for air travel
For air travel, 15-20 mmHg graduated compression knee-high socks are the right choice for most flyers, with 20-30 mmHg reserved for travelers with specific medical guidance from a doctor. The 15-20 mmHg range provides firm enough pressure at the ankle to keep blood moving without being so tight that it becomes uncomfortable over a long flight. If you have a history of DVT, severe varicose veins, or post-surgical recovery, talk to your doctor before choosing a compression level; you may need the firmer 20-30 mmHg range.
Graduated compression means the sock is tightest at the ankle and gradually less tight as it climbs the calf. That pressure gradient helps your veins push blood back up toward your heart instead of letting it pool in your lower legs, which is what causes swelling and increases clot risk during long flights.
mmHg compression level reference
Compression strength is measured in millimeters of mercury (mmHg), the same unit as blood pressure. Here is the quick reference:
8-15 mmHg (mild): everyday comfort, minor leg fatigue, very short flights. 15-20 mmHg (moderate): the standard for air travel, mild varicose veins, pregnancy travel, long work shifts on your feet. 20-30 mmHg (firm): medical-grade, history of DVT, severe varicose veins, post-surgical recovery; usually worn under doctor guidance. 30-40 mmHg (extra firm): prescription-only, serious vascular conditions.
For most travelers, 15-20 mmHg graduated compression is the sweet spot. It is firm enough to do the work, gentle enough to wear for 8+ hours without discomfort, and available over the counter without a prescription.
Material and breathability
Compression socks are made from synthetic blends because natural fibers like cotton do not hold the compression profile well through wear and washing. The most common materials are nylon (durable, moisture-wicking, holds compression), spandex or elastane (the stretch component, usually 15-25 percent of the blend), merino wool (warmer, odor-resistant, less common for travel compression), and copper-infused synthetics (antibacterial, reduces odor on multi-day trips).
For warm cabins and summer travel, look for a breathable knit with some airflow. Dense medical-grade knits trap heat; thinner performance knits breathe better but may feel less firm. The Laite Hebe socks in our roundup were the most breathable of the eight pairs we tested.
Fit, sizing and calf measurements
Sizing is where most compression sock purchases go wrong. Shoe size is a starting point, but calf circumference is what determines whether the top band will sit comfortably behind your knee or dig in. Measure your calf at the widest point, usually a few inches below the knee, and compare to the brand chart. If you sit between sizes, size up.
Wide-calf travelers should look for brands that explicitly offer wide-calf sizing (Levsox, for example) or that run generous in the upper band. The Physix Gear Sport and Iseasoo pairs both held without rolling on my medium-frame calves; for wider frames, the wide top band on the BLUEENJOY and Bluemaple pairs was more comfortable.
For more on how compression fits across activities, our compression shirts guide covers similar sizing principles for upper-body gear.
When to put them on and how long to wear
Put compression socks on 1-2 hours before your flight, before your feet have a chance to swell from sitting in the airport. They are easier to put on when your legs are fresh and dry, and they are far harder to pull on in a cramped airplane seat once you are already boarded. Wear them for the entire flight plus the first 1-2 hours after landing, then take them off.
During the flight, pair the socks with these habits for the best results: drink water consistently to keep blood volume up, do ankle pumps (flex and point your feet) every 30-60 minutes, walk the cabin once an hour if the seatbelt sign allows, and avoid crossing your legs, which compresses veins behind the knee. For long-haul flights over 6 hours, this combination of compression plus movement is what actually reduces DVT risk; the socks alone are not a substitute for movement.
Who should not wear compression socks
Compression socks are not safe for everyone. Skip them and talk to your doctor if you have peripheral neuropathy (you may not feel if the sock is too tight), severe peripheral arterial disease, active skin infections or open wounds on the legs, certain types of heart failure, or untreated deep vein thrombosis. If you have diabetes, talk to your doctor before wearing firm 20-30 mmHg compression. The 15-20 mmHg range is generally safe for most flyers; the firmer ranges warrant medical guidance.
If you are traveling to a cold-weather destination and want warm socks for the flight too, our heated socks guide covers options that pair with compression layering.
Frequently Asked Questions
What level of compression socks is best for air travel?
For most flyers, 15-20 mmHg graduated compression knee-high socks are the right choice. The graduated pressure is firmest at the ankle and eases up the calf, which keeps blood moving without being uncomfortably tight over a long flight. Travelers with a history of DVT, severe varicose veins, or post-surgical recovery may need firmer 20-30 mmHg compression under doctor guidance.
Is 20-30 mmHg compression socks too much for flying?
For most casual flyers, 20-30 mmHg compression is firmer than needed and can feel uncomfortably tight, especially over a long flight. It is the right range for travelers with medical needs (history of DVT, severe varicose veins, post-surgical recovery) and should usually be worn under doctor guidance. If you are new to compression socks, start at 15-20 mmHg and only move up if your doctor recommends it.
When should I put compression socks on before a flight?
Put compression socks on 1-2 hours before your flight, while your legs are still fresh and your feet have not yet swollen from sitting in the airport. They are much easier to pull on at home than in a cramped airplane seat. Wear them for the entire flight plus the first 1-2 hours after landing, then take them off.
How long should you wear compression socks on a plane?
Wear compression socks for the entire duration of the flight, plus 1-2 hours after you land. For long-haul flights over 6 hours, the combination of compression socks plus regular movement (ankle pumps every 30-60 minutes, walking the cabin when allowed) is what actually reduces swelling and DVT risk. Take the socks off once you have arrived at your destination and have moved around.
Who should not wear compression socks when flying?
Compression socks are not safe for everyone. Skip them and talk to a doctor if you have peripheral neuropathy, severe peripheral arterial disease, active skin infections or open wounds on the legs, certain types of heart failure, or untreated deep vein thrombosis. Travelers with diabetes should consult a doctor before wearing firm 20-30 mmHg compression. The 15-20 mmHg range is generally safe for most flyers.
Final Verdict
After testing 8 pairs across multiple flights, the CHARMKING Compression Socks 15-20 mmHg earn our top spot as the best compression socks for flying in 2026. The 8-pair pack covers a full travel week, the 85 percent nylon build holds up through repeated washes, and the 15-20 mmHg graduated compression sits in the sweet spot podiatrists recommend for most flyers. If you need firmer medical-grade compression, the Physix Gear Sport 20-30 mmHg is the right upgrade; if you want the best value-per-pair in a budget multi-pack, the Iseasoo Copper socks deliver the same compression strength at a similar tier with copper-infused odor control.
Whichever pair you choose, put them on 1-2 hours before your flight, drink water consistently, do ankle pumps every 30-60 minutes, and take them off 1-2 hours after landing. That combination of compression plus movement is what keeps your legs comfortable and reduces DVT risk on long flights. Safe travels.
