When your legs need serious therapeutic support without sacrificing an active lifestyle, Jobst ActiveWear delivers. These 30-40 mmHg knee-hi compression socks provide very firm graduated compression — the highest level commonly used for chronic venous conditions, severe edema, and DVT prevention — in an athletic sock designed for all-day wear. Dri-Release® yarn wicks moisture away from the skin to keep feet dry and comfortable, while the seamless toe and 360° cushioned foot make them comfortable enough to wear from morning to night. The non-constricting comfort band holds the sock in place without binding or pinching, and the reinforced heel adds durability for active users. Available in Black and White, in a range of sizes including Full Calf options for wider calf circumferences.
Machine wash in a mesh laundry bag, or hand wash with warm water using a mild soap or detergent designed for compression stockings. Machine dry on low heat.

What is the difference between Standard and Full Calf sizing?
Full Calf variants are designed for users with larger calf circumferences who find standard compression socks too tight or difficult to pull on. If you have a wider calf, the Full Calf option provides the same therapeutic compression with a more comfortable fit through the calf.
Do I need a prescription for 30-40 mmHg compression socks?
In the United States, 30-40 mmHg is a medical-grade compression level. While a prescription is not always required to purchase, it is strongly recommended to consult your physician or vascular specialist before using this compression level, as it is intended for specific clinical indications.
How do I care for Jobst ActiveWear compression socks?
Machine wash in a mesh laundry bag using a mild detergent designed for compression garments, or hand wash with warm water. Machine dry on low heat. Avoid bleach, fabric softeners, and high heat, which can degrade the elastic fibers and reduce compression effectiveness.
How long do compression socks typically last?
Jobst recommends replacing compression socks every 3–6 months with daily wear, as the elastic fibers gradually lose their compression strength over time. Proper washing and drying practices help extend the life of the garment.
