Ideal For

This sock is well suited for men who require firm compression support for conditions such as moderate edema, varicose veins, or chronic venous insufficiency, and who want a product that maintains a professional appearance. It is a practical choice for men who are on their feet for long shifts — including healthcare workers, retail staff, and tradespeople — who need meaningful compression without sacrificing comfort or style. Frequent travelers on long-haul flights will benefit from the 20-30 mmHg compression level, which provides effective support during extended periods of inactivity. The moisture-wicking and anti-bacterial features also make it a strong option for active men who wear compression socks throughout physically demanding workdays.

Frequently Asked Questions

What does 20-30 mmHg compression mean and do I need a prescription?
20-30 mmHg is considered firm compression and is one of the most commonly recommended levels for managing moderate venous conditions, edema, and post-thrombotic syndrome. In many cases, a healthcare provider will recommend this level, though it is available without a prescription. If you are unsure whether this compression level is appropriate for your condition, consult your physician before use.

How do I determine my size?
Measure your ankle circumference and calf circumference in the morning before swelling occurs. The X-Large fits an ankle circumference of 10.5"–12" and a calf circumference of 15"–20". Refer to the Jobst sizing chart if you fall between sizes.

How should I care for these socks?
Machine wash in warm water on a gentle cycle and tumble dry on low heat. Avoid bleach, fabric softeners, and high heat, which can break down elastic fibers and reduce compression effectiveness. Replace every 3–6 months with regular daily use to maintain therapeutic compression levels.

When is the best time to put on compression socks?
Put them on in the morning before getting out of bed or standing up, when leg swelling is at its lowest. This makes application easier and ensures you receive the full benefit of graduated compression throughout the day.
