Frequently Asked Questions

What do the mmHg numbers mean?
mmHg (millimeters of mercury) measures how much pressure the sock applies to your leg. Higher number = stronger compression. Choose based on your need, not personal preference — the wrong level can be ineffective or uncomfortable.
What is graduated compression and why does it matter?
Graduated compression means the pressure is highest at the ankle and gradually decreases up the leg. This is the clinically recommended design — it mimics the natural pumping action of your veins and actively pushes blood upward toward the heart.
Non-graduated (uniform) socks provide less therapeutic benefit. When shopping, look for "graduated compression" on the label to make sure you're getting effective support.

How do I measure myself correctly?
Measure in the morning, before swelling sets in — this ensures the most accurate fit. You'll need ankle circumference, calf circumference, and leg length. For thigh-highs, also measure thigh circumference.
Between sizes? Choose the larger size for your first pair — it's more forgiving and easier to put on. If a sock feels impossible to pull on, the issue is usually compression level, not size.
Who benefits most from compression socks?
If you spend long hours on your feet or sitting without moving, compression socks actively help prevent blood pooling and leg fatigue throughout the day.
How do I care for compression socks?
Hand wash or gentle machine cycle in cold water. Air dry flat — tumble drying breaks down the elastic fibers and reduces compression over time. Avoid petroleum-based creams or lotions on your legs before putting them on, as these degrade the fabric.
Replace every 3–6 months with daily wear. Once the elastic starts to feel loose, the compression level is no longer effective.
