20-30 mmHg Compression Socks for Flying: Medical-Grade Travel Protection
Long flights increase deep vein thrombosis (DVT) risk by 26% for every two hours in the air. Our 20-30 mmHg flying compression collection delivers lab-tested graduated pressure to combat altitude-related leg swelling and reduce blood clot risk. FDA-registered medical-grade compression designed specifically for air travelers facing prolonged immobility, cabin pressure changes, and dehydration during flights.
Why Air Travelers Choose Rescue Legs 20-30 mmHg Compression Socks
Air travel creates unique circulation challenges: cabin pressure drops to 6,000-8,000 feet altitude equivalent, humidity falls below 20%, and cramped seating forces prolonged immobility. Rescue Legs 20-30 mmHg flying compression socks address these specific risks with medical-grade graduated pressure that works throughout your journey.

Why Flying Demands 20-30 mmHg Compression
Flight duration and personal risk factors determine which compression length and style provides optimal protection against in-flight blood clots and leg swelling.
Domestic Flights
- Even short flights create circulation challenges.

Choosing Your Flying Compression:
Size & Style Guide
Getting the best results from flying compression starts with correct sizing. Air travel swelling makes proper fit even more critical than daily wear compression.
How to Measure
Best time: Measure in the morning before swelling develops. If you've just landed, wait 24-48 hours for measurements to normalize.
- Ankle: Around the narrowest part, just above the ankle bone.
- Calf: Around the widest part of your calf.
- Thigh: Around the widest part of your thigh (for thigh-highs).

Flying Compression Questions
For flights under 2 hours with no risk factors, 15-20 mmHg may suffice. However, 20-30 mmHg provides superior protection with no downside if properly fitted. Many travelers prefer it to avoid guessing.
Properly fitted 20-30 mmHg should feel snug but not painful. Most travelers report legs feeling LESS uncomfortable because the pressure prevents the aching sensation caused by blood pooling.
Keep them on during short layovers (under 3 hours). Walking around the airport with compression provides excellent circulation benefits. For longer layovers (6+ hours), you can remove for 2-3 hours.
