How we chose
- A clearly stated mmHg range, not vague strength language
- Sizing charts that use calf circumference as well as shoe size
- Cuffs that hold without digging in
- Fabric that survives repeated cool washes
- Honest usefulness on flights over five hours
The picks
1. Start here
Graduated compression socks (15–20 mmHg)
Budget, $15–$35 per pair
A 15–20 mmHg graduated knee-high is the standard travel choice and the item most long-haul travellers notice immediately on landing.
Worst thing about it: Fiddly to pull on, especially with hand or back problems
2. Best cheap add-on
Under-seat foot hammock
Budget, $15–$30
Supporting your legs rather than letting them dangle changes hip angle and reduces the heavy-leg feeling, for the price of a paperback.
Worst thing about it: Not usable on every seat, and some crew will ask you to stow it
3. Best supporting habit
Electrolyte drink packets
Budget, $1–$2 per serving
Compression works alongside actually drinking enough. Making water appealing is the easiest way to do that in dry cabin air.
Worst thing about it: The sodium load matters if you have high blood pressure or kidney issues
4. Best for hip and tailbone pressure
Travel seat cushion
Mid-range, $25–$60
If your legs ache because your hips are taking all the pressure, a cushion helps more than tighter socks will.
Worst thing about it: Raises you up, which can make the headrest sit wrong
Common questions
- What mmHg compression socks are best for flying?
- 15–20 mmHg graduated compression is the usual travel range. Higher strengths are medical devices; ask your doctor if you have clot history, diabetes, peripheral artery disease, or recent surgery.
- Do I need knee-high or thigh-high compression socks for flights?
- Knee-high is the practical choice for travel. Thigh-highs are harder to keep in place and more likely to roll or dig in, which defeats the purpose.
- When should I put compression socks on before a flight?
- Before you leave home, while your legs are least swollen, and keep them on through transit until you arrive.
