Why Natural Rubber with Open Toe for Class 3 Compression

Natural rubber compression stockings with open-toe design combine exceptional therapeutic pressure delivery with practical patient benefits essential for managing severe venous conditions requiring 30–40 mmHg Class 3 compression. Natural rubber's inherent elastic properties provide superior containment force and durability compared to synthetic compression materials, maintaining consistent graduated pressure throughout extended wear periods and multiple washing cycles—critical for patients requiring long-term daily compression therapy. The open-toe construction serves multiple therapeutic purposes: enables foot circulation assessment without stocking removal, accommodates patients with toe deformities or sensitivity, provides temperature regulation during warm weather, allows sizing flexibility for varied foot lengths, and facilitates easier donning of extremely firm compression. Sigvaris 503N specifically engineers medical-grade natural rubber with silicone grip-top technology to prevent the downward migration that commonly occurs with thigh-high Class 3 compression during daily activities.

Application Technique - Open-Toe Thigh-High:

• Gather stocking accordion-style from top to toe opening
• Insert foot through toe opening
• Position fabric under forefoot and around heel
• Natural rubber requires significant pulling force
• Work gradually up foot to ankle with steady pressure
• Continue up calf to knee area
• Stand to pull over knee to thigh
• Ensure silicone grip-top reaches proper thigh position
• Top band should sit 2–3 inches below gluteal fold
• Smooth all wrinkles thoroughly—extremely important
• Toes should be comfortable and uncovered

Silicone Grip-Top Management:

• Grip-top band contains silicone for adhesion to skin
• Position band flat against thigh without rolling
• Silicone should contact clean, dry skin for maximum grip
• Avoid lotions or oils on thigh before application
• Band prevents stocking from sliding down during activity
• Check periodically that band hasn't rolled or shifted
