I have worn these toe-out stockings for 20+ years. Once I found the toes-out version, I no longer had pinched toes in order to have compression on my legs and ankles. I highly recommend them

I've been wearing Sigvaris 30-40 for the past 10 years plus. The only problem I've experienced was the top band had a tendency to roll down and pinch my calf's, almost a tourniquet effect. the only solution was to replace them more frequently. The cost for a senior on a fixed income was hard felt. I contacted Sigvaris customer care/service and was guided to the style that had a wider band with silicon dots that completely took care of that problem. The company even replaced the problem stocking's at no cost. Moshe and staff at Discount Surgical really go out of their way to be helpful and curtious.

I have worn anti-emboli stockings for 23 years. These are the best. I especially like that they are open toe.

I have worn Sigvaris compression stockings for more than 20 years. They are consistently high quality and always fit, once one is initially measured. Proper washing care is very important to maintain the integrity of the compression. I recommend 2 pair, one to be worn while the other is being washed and air dried. I buy 2 pair of each color I want. New stockings should be obtained at least every 6 months.

I've been using this product for the last 12 + years. At first the top of the hose stretched out, causing them to roll down and bind my calf's. The mfg. has made the tops wider and that problem for the most part has been taken care of. With rubber gloves they go on easy enough and are very comfortable to wear. they are a little expensive and need to be replaced as the mfg. suggests.

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.
