M4 Sizing
For the 503C M4 configuration, accurate ankle and calf measurements are essential. Published sizing information for the M4 configuration lists an ankle circumference of approximately 9–12 inches and a calf circumference of over 19 inches; the Full Long option corresponds to the longer applicable calf/leg length.
Do not select M4 based on shoe size or general clothing size alone. Compression garments at 30–40 mmHg should be fitted using the manufacturer's sizing system and the patient's actual measurements.
Natural Rubber & Allergy Information
This product is identified as Natural Rubber. Natural rubber products can contain natural-rubber latex proteins. Anyone with a known latex allergy or sensitivity should confirm the material composition with the manufacturer or healthcare professional before use.
Do not rely on a third-party listing that describes the product as latex-free when the manufacturer's device record identifies the product as natural rubber. The exact 503CM4O77 configuration should be verified from the product label if latex status is clinically important.
Usage, Care & Safety Information
30–40 mmHg is extra-firm compression. Use under appropriate clinical guidance, particularly for patients with arterial disease, diabetes-related complications, significant edema or other conditions where compression may require medical assessment.
Put the stocking on according to the manufacturer's fitting instructions, preferably when swelling is lowest. Smooth the garment evenly and avoid folds, bunching or rolled edges.
Inspect the skin regularly. Remove the garment and seek clinical advice if there is significant pain, numbness, discoloration, unusual coldness or worsening symptoms.
Follow the manufacturer's laundering instructions. Avoid bleach, fabric softener and excessive heat unless specifically permitted by the manufacturer.
