Understanding Compression Levels

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.

MILD 8-15 mmHg Travel, tired legs, everyday wear
MODERATE 15-20 mmHg Mild swelling, varicose veins, athletes
FIRM 20-30 mmHg DVT prevention, post-surgery, edema
EXTRA FIRM 30-40 mmHg Prescribed only — doctor supervision required

Mild: Energizes tired legs, ideal for travel and everyday wear
Moderate: Reduces mild swelling, helps with early-stage varicose veins, great for athletes and frequent travelers
Firm: Medical-grade compression for moderate to severe varicose veins, DVT prevention, post-surgery recovery, and edema management
Extra Firm: Prescribed for severe conditions like chronic venous insufficiency and lymphedema

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.

Which length should I choose?

KNEE-HIGH
  • Most popular choice
  • Covers the calf muscle
  • Great for daily support & travel
THIGH-HIGH
  • Extended upper leg coverage
  • For circulation above the knee
  • Often prescribed post-surgery
PANTYHOSE / LEGGINGS
  • Full leg + waist support
  • Ideal for pregnancy
  • All-day wear coverage
FOOTLESS
  • Better breathability
  • Allows toe inspection
  • Wear with open-toe shoes
CLOSED TOE
  • Full foot coverage
  • Standard option for daily use
  • Recommended for most medical conditions

What materials should I look for?

  • Look for breathable fabrics like nylon-spandex blends
  • Moisture-wicking properties keep legs dry
  • Reinforced waistband and crotch prevent slipping and tearing
  • Opaque fabric provides coverage while healing

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.
