Why Choose the Sigvaris® 503N Natural Rubber?
The 503N Natural Rubber series uses double-covered elastodiene yarn made from natural rubber. Sigvaris' product information describes the material as highly elastic and designed to maintain compression over extended wear. This makes the series suitable for users who require consistent extra-firm compression.
The thigh-high configuration extends from the foot to the thigh and uses a silicone grip-top to help maintain position. The open-toe design leaves the toes exposed, which can be useful for footwear preferences and visual access to the toes.

Sizing & Fit
M4 identifies the medium circumference configuration, while Full Long identifies the longer length option. Compression garments should be selected using accurate measurements and the manufacturer's sizing chart rather than by shoe size alone.
For 30–40 mmHg compression, professional fitting is strongly recommended. An incorrectly sized garment can be difficult to apply or may not provide the intended compression profile.
Natural Rubber & Latex Information
This garment contains 30% natural latex rubber. It is not latex-free. Anyone with a known or suspected latex allergy should avoid the product unless a qualified healthcare professional specifically advises otherwise.
The natural rubber construction is different from synthetic compression garments and has different care and handling requirements. Follow the manufacturer's care instructions to preserve elasticity and compression performance.
Usage and Safety Information
Use 30–40 mmHg compression only when clinically appropriate and according to the prescriber's or qualified fitter's instructions. Confirm circulation status and contraindications before dispensing.
Apply the stocking smoothly without folds, bunching or rolled edges. Do not cut or modify the garment or the silicone grip-top.
Check the skin regularly, especially during initial use. Remove the garment and seek clinical advice if significant pain, numbness, unusual colour change, skin damage or other concerning symptoms develop.
Latex warning: Contains natural latex rubber. Do not use for individuals with a known latex allergy.
Follow the manufacturer's washing and drying instructions. Avoid bleach, fabric softeners, high heat and other treatments that can damage natural rubber or the garment's elastic properties.
