Compression socks are one of the most evidence-backed travel accessories you can buy. On flights over four hours, sitting still with your legs bent reduces blood flow in the lower legs, which increases the risk of deep vein thrombosis (DVT) and causes the swelling and heaviness that makes you feel terrible when you land. Graduated compression socks apply gentle pressure that keeps blood moving and significantly reduces both risks.

Compression Socks vs Regular Travel Socks
Compression Travel Socks
Apply graduated pressure — tightest at the ankle, gradually reducing up to the leg — to support venous return and keep blood circulating during long periods of sitting. Measured in mmHg (millimetres of mercury). For travel, 15–20 mmHg is the standard range: enough to make a real difference without being uncomfortable or requiring a prescription. Higher compression levels (20–30 mmHg and above) are medical-grade and typically require a doctor's recommendation.
Merino Wool Travel Socks
Not compression socks, but excellent for travel. Merino wool regulates temperature (warm in cold conditions, cool in warm conditions), resists odour after multiple wears, and is soft enough to wear all day without discomfort. A good merino travel sock can be worn for 2–3 days between washes — genuinely useful for carry-on-only travel where you're minimising laundry.
Who Should Wear Compression Socks on Flights?
The Australian and New Zealand College of Anaesthetists recommends compression stockings for all travellers on flights over 4 hours, and particularly for those with additional DVT risk factors including:
- Previous DVT or pulmonary embolism
- Recent surgery or injury
- Pregnancy
- Active cancer or cancer treatment
- Obesity (BMI over 30)
- Use of oral contraceptives or hormone replacement therapy
- Age over 60
If you have multiple risk factors, speak to your GP before long-haul travel about whether higher-compression medical-grade stockings are appropriate.
How to Choose the Right Compression Level
-
8–15 mmHg: Light compression, suitable for everyday wear and mild swelling. Good for shorter flights and travellers with no specific risk factors
-
15–20 mmHg: Moderate compression, the standard for travel. Recommended for flights over 4 hours for most travellers
-
20–30 mmHg: Firm compression, medical-grade. Requires a doctor's recommendation for most people
Frequently Asked Questions
Do compression socks actually prevent DVT?
Yes — there is good clinical evidence that graduated compression stockings reduce the incidence of DVT on long-haul flights. A 2016 Cochrane review found that compression stockings significantly reduced the risk of symptomless DVT in airline passengers. They won't eliminate the risk entirely, but they're one of the most effective preventive measures available without a prescription.
How tight should travel compression socks be?
Compression socks should feel firm but not painful. At 15–20 mmHg, you should feel noticeable pressure at the ankle that gradually reduces up the leg. If they're cutting off circulation, causing numbness, or leaving deep marks, they're too tight or the wrong size. Always size by calf circumference and ankle circumference, not shoe size.
Can I wear compression socks on a short flight?
Yes — there's no harm in wearing compression socks on short flights. The benefit is most significant on flights over 4 hours, but wearing them on shorter flights won't cause any problems for healthy travellers.
