Key Features

• Extra-Firm Medical Compression (30-40 mmHg): Provides the highest class of graduated pressure, medically prescribed for severe venous hypertension, significant edema, and active ulcer management.
• SoftFit Band for Essential Security: The silicone-blend band is therapeutically necessary at this pressure level, preventing roll-down and migration to maintain the precise graduated pressure gradient from ankle to knee.
• Medically Durable Construction: Built with a robust fabric blend (higher spandex content) and heavily reinforced heel and toe to withstand the substantial forces of high-compression therapy.
• Elegant Opaque Coverage for Discretion: Maintains the concealing, hosiery-like appearance, providing a psychological and cosmetic benefit during intensive medical treatment.
• Closed Toe for Complete Foot Coverage: Offers full foot encapsulation, which is often preferred in high-compression therapy for uniform pressure distribution and protection.
• Moisture-Wicking for Skin Integrity: Critical fabric technology helps manage moisture under the opaque material, supporting skin health during extended wear periods.
• 3D Medical Knit for Controlled Donning: Engineered for specific elasticity, aiding in the challenging application process while ensuring the pressure profile remains accurate.
• Medical Device Standards: Manufactured as a Class 3 medical device, meeting stringent requirements for compression therapy in wound care and advanced venous/lymphatic disease.

Therapeutic Benefits and Use

• Manages Severe Chronic Venous Insufficiency (CVI): Delivers sustained high pressure to combat profound venous reflux, ambulatory venous hypertension, and associated skin changes like lipodermatosclerosis.
• Active Venous Leg Ulcer Healing: A critical component of evidence-based compression therapy, providing the uninterrupted high pressure required to heal venous ulcers by improving microcirculation.
• Controls Severe Edema and Lymphedema: Applies strong, stable compression to reduce substantial limb volume, soften fibrotic tissue, and maintain results from decongestive therapy.
• Prevention of Venous Ulcer Recurrence: Essential maintenance therapy after ulcer healing, with high compression proven to significantly reduce reoccurrence rates.
• Post-Thrombotic Syndrome (PTS) Management: Helps alleviate the disabling pain, swelling, and skin damage caused by PTS following a deep vein thrombosis (DVT).
• Ensures Effective Treatment Delivery: The SoftFit band's secure fit is not a comfort feature but a therapeutic requirement for 30-40 mmHg compression to work as prescribed, preventing harmful pressure concentration.
• Supports Intensive Lymphedema Protocols: Used to maintain compression between complete decongestive therapy (CDT) sessions, preventing fluid reaccumulation in severe cases.
• Manages Manifestations of Advanced Disease: Addresses symptoms such as severe aching, heaviness, night cramps, and skin breakdown associated with advanced venous disorders.

Important Medical Notice

This is a Class 3 prescription medical device. Physician evaluation, approval, and precise medical sizing are mandatory. Contraindications include severe arterial insufficiency (ABPI must be assessed and should be > 0.5), acute deep vein thrombosis, untreated cellulitis or infection, uncompensated congestive heart failure, or known silicone allergy. Do not use if it causes severe pain, numbness, coldness, or discoloration of toes or feet. Regular medical monitoring is required when using extra-firm compression. Your vascular specialist or wound care physician can determine if this compression level is appropriate for your condition.

Frequently Asked Questions

Why is the band so important at 30-40 mmHg?
At this high compression level, the fabric exerts a strong downward force. A secure band is therapeutically essential to prevent the stocking from rolling down, which would concentrate dangerous pressure at the knee and render treatment ineffective. The SoftFit band is designed for this critical function.

What donning aids are required for these stockings?
Donning aids are strongly recommended, often essential. Use donning gloves, a metal or plastic frame donner, or a stocking slide. Accurate sizing per our guide is critical for both safety and the ability to don the garment.

Can these be worn over wound dressings?
Yes, they are commonly prescribed as part of multilayer compression bandaging systems or over ulcer dressings. Ensure the dressing is smooth and not bulky. Always follow your wound care specialist's specific instructions for wear and dressing changes.

How does the SoftFit band differ from a standard silicone band?
The SoftFit band is engineered with a specific blend and knit structure to provide the necessary secure hold while aiming to distribute pressure more comfortably, which can enhance wearer tolerance during long-term high-compression therapy.

What is the typical wearing schedule?
Usually worn during waking hours (approximately 12-16 hours per day) and removed at bedtime, unless a physician specifies a different protocol for an acute condition like an active ulcer.

Who should absolutely not use this compression level?
Contraindications include significant arterial disease (PAD) without prior assessment, acute DVT, uncontrolled heart failure, or widespread skin infection. An arterial Doppler (ABPI) test is typically required before prescription.
