Understanding the right compression level is essential when choosing compression socks for daily use, travel, or medical purposes. Compression is measured in mmHg and offers graduated compression to support blood flow, reduce swelling, and improve recovery.

1. Light Compression (8-15 mmHg)

• Light support for daily wear
• Helps relieve fatigue and minor swelling
• Recommended for: Work, travel, or long hours standing

2. Moderate Compression (15-20 mmHg)

• Prevents spider veins, leg fatigue, and ankle swelling
• Supports circulation during flights or exercise
• Recommended for: Frequent flyers, light varicose veins, mild edema

3. Firm Compression (20-30 mmHg)

• Medical-grade level for DVT prevention, post-surgery recovery, and varicose veins
• Recommended for: Athletes, surgical patients, or those with moderate vein issues

4. Extra Firm Compression (30-40 mmHg)

• Enhances venous return and treats moderate to severe edema
• Recommended for: Pregnant women, DVT recovery, phlebitis, vein disorders

5. Severe Compression ( Above 40 mmHg)

• For serious venous conditions, lymphedema, and ulcers
• Recommended for: Chronic venous insufficiency, post-thrombotic syndrome

For best results, get measured and seek advice from a healthcare provider.

Quick Guide: How to Put On Compression Socks

• Wearing compression running socks correctly is essential to ensure effective graduated compression and comfort during physical activity.
• Start by rolling the sock down to the heel, keeping it right-side out.
• Gently insert your foot, making sure the heel and toe align properly.
• Slowly pull the sock up your leg, smoothing out any wrinkles to avoid uneven compression.
• The sock should feel snug but not overly tight, especially around the ankle and calf.
• Proper fit ensures optimal circulation support and helps maximize the performance of your compression socks throughout the day.

Proper compression socks care ensures long-lasting compression and comfort:

• Wash at temperatures below 40°C (104°F) to prevent fiber damage.
  
• Avoid bleach and fabric softeners, as they degrade compression and materials.
  
• Machine wash with care:
  
  • Use a laundry bag
  • Select gentle cycle under 30°C
• Do not iron or dry clean — heat and chemicals can weaken elastic fibers.
  
• Drying tips:
  
  • Use low-heat mode if using a dryer
  • Air dry flat, away from direct sunlight or heat sources
• Proper care helps preserve compression levels and extend product life.

As an experienced compression socks manufacturer, we support flexible production planning to help growing brands launch with confidence. For larger programs or multiple styles, MOQ may be discussed case by case.

As experienced compression hosiery manufacturers, we explain the difference between graduated and uniform compression as follows.

1. Graduated compression socks:

• Graduated compression applies the highest pressure at the ankle
• Gradually decreasing up the leg

This design is ideal for medical and athletic purposes. 

2. Uniform compression socks:

• Consistent pressure throughout the sock

Offering general support but less effective blood flow promotion.
