I've been wearing these for years now. Over the past 15 years I have developed circulation problems in both legs that require use of support socks. I live an active lifestyle and go on very long day hikes on Saturdays (in the 20-25 mile range). These socks give me the support I need to get out and enjoy life.

Helps my feet and toes feel alot better when I'm on them all day. My calves of my legs are more relaxed when I remove them at night. Great support and comfort.

I have been wearing High Compressions socks for over 35 years. Recently I orederd a pair of JOBST model FMKN3-4 High Compression socks. I can definitely say that these socks are the best, truly EXCELLENT. They put the right pressure where it's needed and at the end of the day, when you take them off, your feet and legs are absolutely not tired or swoolen. EXCELLENT PRODUCT.

Q & A

Ask a Question
2 questions for this item
Q: What size for a shoe size 11-12
A: Large
Q: What's the difference between XL full calf and XL?
A: XL Full Calf is for a person that has a big calf. It all depends on the measurements of the calf. If you look at the size chart on the item you will see what size you belong according to your measurements.
Questions that are on Your Mind
Q: Can you help me with sizing?
A: You can view the size chart here: size chart
You will need accurate measurements, so first learn how to measure.
Q: What is compression? What is the difference in compression?
A: You wear compression stockings to improve blood flow in your legs. Compression stockings gently squeeze your legs to move blood up your legs. This helps prevent leg swelling and, to a lesser extent, blood clots.
Q: What does mmHg mean?
A: mmhg stands for "millimeter of mercury", a way to measure pressure. The higher the number, the tighter the garment will squeeze and the more compression it provides.
Q: How can we wash the garments? And with which soap or detergent?
A: We recommend to hand wash in warm water and air dry. You can use mild soup of the washing solution that we provide such as the jobst jolastic, hosiery mate washing solution, sigvaris liquid washing solution etc. See our full washing instructions.
Q: What is the difference between open toe and close toe?
A: There is no therapeutic difference between open and closed toe socks. The choice is yours, whichever is more comfortable.
Q: What is opaque?
A: Opaque is a thicker material that provides great coverage and your skin will be far less visible. Usually worn in winter because of the thickness.
Q: What is sheer?
A: Sheer is a thinner, dressier material. Customer usually like these because they can use them as dress socks for work or church.
Q: Do I get compression at the toe area?
A: No. Compression begins at the ankle and gradually lessens as it goes up the leg. This reduces pooling in the legs and helps the veins return blood to the heart.
Q: Will a thicker material give me more support than the sheer material?
A: No. The compression provided is measured by mmHg and is the same no matter the material. The choice of material is up to you, whichever is more comfortable.
Q: If I get pantyhose will I get more compression than with a knee-hi?
A: No.
Q: Where are you? How's the weather?
A: We are located in Brooklyn, NY. Here is the current weather in our part of town. We hope the sun is shining by you!
