Stockings for long journeys and why legs swell on a plane
Short answer: Legs swell on long journeys because you sit still for hours without using the calf muscle. Without that pump, fluid collects in the lower legs, and you feel it as heavy, tight ankles by the time you leave the plane.
The calf muscle is the pump
Every time you walk, the calf muscle contracts and pushes blood up the leg. When you sit still, the pump stops. That is why swelling appears on planes, trains and long car journeys, whatever your age or fitness. It is not about how healthy you are, but how long your legs stay still.
Why it shows most on a plane
On a plane you often sit in a tight space, knees bent, with no room to stretch your legs. The seat edge can press under the thighs, and you stand up less often than on a train. Together that makes it easy for fluid to stay down in the legs for hours at a time.
What the stockings do
A stocking with even pressure, strongest at the ankle and easing off higher up, takes over part of the pumping work the calf muscle usually does. It makes it harder for fluid to collect, and many find their ankles feel lighter on arrival. See bamboo support stockings.
Put them on before you leave
Put the stockings on in the morning before leaving home, while your legs are not yet swollen. Pulling on a close fitting stocking in a cramped plane seat is awkward, and swollen ankles make it harder still. Check that the heel sits correctly and the top band lies flat without digging in.
What you can do yourself
Stand up every hour if you can and walk down the aisle. Pull your toes towards your shin a few times an hour while seated, and drink water along the way. It does more than any stocking on its own. Socks for the rest of the trip are in all bamboo socks for women.
Clothes and shoes for the journey
Choose loose clothing without a tight waistband, and shoes that are easy to loosen if your feet swell. Avoid socks with a tight cuff around the calf, as it works the opposite way to a support stocking. A fabric that moves moisture away from the skin makes long hours more comfortable.
When to ask a doctor
If you have had blood clots, are pregnant, have recently had surgery or take medication that affects circulation, talk to your doctor before a long journey. Ordinary stockings are not medical compression. The everyday styles for men are in all bamboo socks for men.
After landing
Take a short walk once you have landed instead of sitting straight down in a taxi or bus. Movement quickly gets the calf muscle working again. Raising your legs a little in the evening can also help. Swelling after a flight usually goes down within a day, and if it does not, have it checked.
Washing after the trip
Support stockings last longest when washed at a low temperature and hung to dry. Heat from a tumble dryer wears down the elastane, so the stocking loses its pressure sooner. If you pack two pairs for a longer trip, one can dry at the hotel while you wear the other.
Frequently asked questions
Why do legs swell on a plane?
Because the calf muscle does no work while you sit still with bent knees for many hours, so fluid collects in the lower legs and ankles.
Do support stockings help on flights?
They can reduce swelling and the heavy feeling. Moving every hour, doing foot exercises and drinking water along the way still help more than the stocking alone.
Who should talk to a doctor before a long journey?
People who have had blood clots, pregnant travellers, anyone who has recently had surgery and people on medication that affects circulation. They should get advice before travelling.
