I purchased a pair of Sigvaris cotton thigh highs and they are the best fiiting stocking I have purchased. Better than Juno and several others. They are washable, tough and provide great support.

Great compression hose for my lymphedema

Stockings do a good job of compressing.. I wish they were a couple inches shorter on the thigh end. I developed sores from the new models with the continuos silicone band. I have always been pleased with the service of Discount Surgical Warehouse.

The socks arrived sooner than expected. They fit better than Jobst's "relief". I have been wearing support hose for 12 years. Hopefully we'll see if the cotton relieves the skin irritation.

I've finally given over to wearing compression stockings all of the time. That means summers in San Diego which is difficult. The high cotton content in these stockings is comfortable during warm weather and the matt look of the knit looks more appropriate with my work and casual attire during summer months. This brand is expensive but with a drawer full of various brands, they are by far my favorite with the best quality and fit.

Q & A

Ask a Question
1 question for this item
Q: Are these stockings latex free? Is it safe to use petroleum based creams/lotion? If not, what moisturizer do you recommend to apply to legs prior to putting on stockings? THANKS!
A: The stockings are latex free. We recommend to use the mediven leg night cream model number 979 on our website
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.
