Nooni Compression Socks

Everyday brands like this typically offer graduated compression in the 15–20 mmHg range, the standard over-the-counter level for travel and general circulation support. True medical-grade support (20–30 mmHg or higher) usually requires professional fitting.

Yes, that's the core use case—15–20 mmHg graduated socks are commonly recommended for long-haul flights to reduce swelling and lower the risk of circulation problems from prolonged sitting. Put them on before boarding rather than mid-flight for the best effect.

The elastic fibers in graduated compression socks degrade with heat, so most makers advise cold washing and air drying rather than using a dryer. Hand washing extends the life further, and expect to replace any compression sock every few months of regular wear as the spandex loses tension.

Light 15–20 mmHg compression can ease the aching and swelling of mild varicose and spider veins, which is why it's the common everyday level. If you have diagnosed venous insufficiency, a clinician may prescribe 20–30 mmHg or stronger instead.
