20-30 mmHg
Firm/Medical-Grade CompressionBest for:
- Moderate to severe varicose veins
- Moderate to severe edema (leg swelling)
- Post-surgical recovery
- DVT prevention (high-risk patients)
- Lymphedema management
- Chronic venous insufficiency
Who should use: People with diagnosed medical conditions. Consult your doctor before using this level.
Note: More difficult to put on and remove. May require assistance or donning tools.
30-40+ mmHg
Extra Firm CompressionBest for:
- Severe chronic venous insufficiency
- Severe edema and lymphedema
- Post-thrombotic syndrome
- Severe varicose veins
Who should use: Only under medical supervision. Requires prescription in most cases.
⚠️ Warning: Do not use this compression level without consulting a healthcare professional. Improper use can restrict circulation.

8. Avoid These Common Mistakes
❌ Mistake #1: Choosing Too High Compression
The problem: People think "more compression = better results" and jump straight to 30-40 mmHg without medical need.
Why it's wrong: Excessive compression can restrict circulation, cause pain, and be dangerous for certain conditions.
✅ Solution: Start with 15-20 mmHg unless your doctor recommends higher. You can always increase if needed.
❌ Mistake #2: Guessing Your Size
The problem: Buying based on shoe size or regular sock size without measuring.
Why it's wrong: Compression socks must fit precisely to work. Wrong size = ineffective or dangerous.
✅ Solution: Always measure ankle, calf, and height. Follow the manufacturer's size chart. When in doubt, ask for help.
❌ Mistake #3: Buying Based on Price Alone
The problem: Choosing the cheapest option or assuming expensive = better.
Why it's wrong: Very cheap socks likely aren't true compression. Very expensive may include features you don't need.
✅ Solution: Focus on medical certifications and proper specifications. Quality compression socks typically cost $20-50 per pair.
❌ Mistake #4: Wrong Length for Your Needs
The problem: Buying ankle socks for varicose veins or knee-high for just foot pain.
Why it's wrong: Compression must cover the affected area. Ankle socks won't help calf issues; knee-high is unnecessary for just feet.
✅ Solution: Match length to where you need support. When in doubt, knee-high covers most use cases.
❌ Mistake #5: Not Reading Care Instructions
The problem: Washing in hot water, using fabric softener, or machine drying.
Why it's wrong: Heat and chemicals destroy elastic fibers, making socks lose compression.
✅ Solution: Hand wash or gentle cycle, cold water only, air dry flat. Follow care instructions to maximize lifespan.
❌ Mistake #6: Wearing Them Wrong
The problem: Putting socks on like regular socks, causing bunching and discomfort.
Why it's wrong: Improper application reduces effectiveness and comfort. Bunching can create pressure points.
✅ Solution: Turn inside-out to heel, slide foot in, gradually roll up. See our how to wear guide.
❌ Mistake #7: Giving Up Too Soon
The problem: Trying compression socks once, finding them tight, and never wearing them again.
Why it's wrong: Compression socks feel different from regular socks. There's a brief adjustment period.
✅ Solution: Wear for 2-4 hours the first few times. Your body will adjust. If still uncomfortable after a week, reassess size.
❌ Mistake #8: Using One Pair for Everything
The problem: Wearing the same compression socks for work, sports, and medical conditions.
Why it's wrong: Different activities may need different compression levels or features.
✅ Solution: Consider having 2-3 pairs: one for daily wear, one for sports/specific activities, one as backup while washing.
