Everything is good with these compression hose except when I bend my knee, the top rolls somewhat (all brands do on me). Not sure if that is good for circulation but I have to have compression hose, so ---

The Jobst Knee-high stockings have a very nice, soft fabric - which is very important for those with varicosities over the medial malleolus. The top band on the Jobst knee high stockings is wider than some and so makes the fit more comfortable.

I have purchased this stocking for years. They were wonderful in the past. I was told that the "natural" color was the same as "silky beige". It is very yellow and dull compared to the "silky beige" which has a pink cast that more closely matches my skin tone. I will not buy these again until they bring back the "silky beige". They are softer, which felt better. However, they did not hold up and last nearly as long as the old stockings. They pilled and I wore a hole in the heel way too fast...... Not satisfied!

PLEASE make these in sheer/less support. These fit so well around my fat calves, no pinching like the size XL causes. Most of us would like a sheer because the opaque color is not very natural looking. The less support (< 20mmHG) type would be nice to have since they are not available anywhere that I shop.

I recently purchased and returned (great customer service) two pairs of Jobst Opaque knee high open toe 30-40 stockings. I have purchased at least 10 pairs in the past and LOVED the color has changed and silky beige is no longer available and they come in what is listed as Natural. They tried to tell me it was the same color, so I ordered them anyway and NO They are tan, and my light skin color, they remind me of what my grandma used to wear. They also are made of a different blend. The cuffs were both balled after the first washing and they had pin sized holes in the cuffs. These are NOT the same great stockings as in the past and I am no longer going to purchase this obviously inferior product. I would have paid more to purchase the better quality, but now they lost a customer.

Q & A

Ask a Question
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.
