Compression socks for travel and flights
Updated 2026-09-08 · 6 min read · All guides
General information only — not medical advice. If you are unsure whether compression is suitable, ask a clinician first.
Why travellers look at flight socks
Long periods of sitting — flights, trains, car journeys — can leave legs feeling heavy. Mild graduated compression socks are a common travel accessory. They are one comfort tool among many, not a guarantee against serious clots.
Sensible travel habits (alongside socks)
- Walk the aisle when safe and allowed
- Ankle pumps and calf stretches in your seat
- Stay hydrated; go easy on excess alcohol
- Wear clothes that do not constrict the waist or legs
Choosing for a trip
Many travellers pick a moderate consumer range (often marketed around 15–20 mmHg) in a knee-high with a clear size chart. Put them on before you board if that is your plan, and remove them if they cause pain or numbness.
Higher-risk travellers
If you have a history of clots, recent surgery, cancer treatment, pregnancy-related concerns, or other risk factors, speak to a clinician before relying on any garment. Medication or other measures may be advised instead of — or as well as — socks.
