Maximum Containment for Severe Lower Leg Disease
The Sigvaris Natural Rubber 40-50 mmHg class (often categorized as Class III) is a clinical-grade garment intended for use when standard firm compression is insufficient. The 100% natural rubber material provides an extremely high stiffness (high “working pressure”), which is paramount for effectively reducing and maintaining the reduced size of limbs affected by severe, chronic, non-pitting edema and advanced lymphedema.
This knee-high style focuses the maximum pressure on the lower leg—the primary area affected by gravity and fluid pooling—while providing a design that is practical for daily wear.
Key Features and Benefits
| Feature | Benefit |
| 40-50 mmHg Extra-Firm Compression | Benefit: Provides the highest commonly prescribed pressure level, crucial for managing the most severe and fibrotic vascular and lymphatic conditions in the lower leg. |
| Natural Rubber Fiber | Benefit: Delivers superior containment and stiffness, essential for controlling severe, non-yielding edema more effectively than softer, conventional synthetics. |
| Knee High Length (AD) | Benefit: Concentrates maximum pressure on the ankle and calf, offering targeted and aggressive therapy where fluid pooling is most challenging. |
| Open Toe Design | Benefit: Allows for easy visual inspection of the toes and skin, increases comfort by accommodating various foot sizes, and improves overall breathability. |
| Durable Construction | Benefit: Engineered to maintain its therapeutic pressure level, enduring the high stress required for donning and the demands of severe swelling containment. |
| Comfortable Top Band | Benefit: Features a non-binding top band that holds the stocking securely in place without restricting circulation at the back of the knee. |
Critical Indications for Use
This 40-50 mmHg stocking requires a medical prescription and professional fitting.
It is used to manage:

⚠️ Safety and Fitting Requirement
As an extra-firm compression garment, professional measurement and fitting by a certified fitter or physician are mandatory. Do not wear this high level of compression unless prescribed and properly fitted, as improper use can lead to serious health issues. Always consult the Sigvaris sizing chart and your healthcare provider.
