Severe lymphedema in right leg only for decades; this Sigvaris stocking is the strongest support I've found to effectively manage swelling. Not the prettiest but, the most effective. It's my go-to after wearing the prettier ones for awhile. Prettier ones manage well also but, for me, these are the most effective.

I have been wearing knee hi for years for lymphedema in left leg. Since having a total knee replacement, the swelling was redistributed when I wore the knee hi. I ordered the thigh hi to balance the swelling over the knee. I am so pleased! Now I have graduated compression from my foot over the swollen knee to my thigh. I wish I had thought of ordering this earlier.

I have severe lymphedema in RT leg...from ankle to thigh. This stocking is most effective in controlling fluid buildup. Not the prettiest, but the most effective! I wear stocking all the time except when I'm bathing. The only problem I've experienced is the roll over/down of the silicone band @ top. Never had this problem until recent years. The last pr I bought is working better.

Adquiri a meia Sigvaris de compressão 40-50 e o tamanho recomendado pelo sistema automática de informação de medidas. Achei a meia muito grossa. Talvez seja perfeita para pessoas que vivem em locais com temperatura baixa. Mas como moro no Rio de Janeiro, onde a temperatura é ultra quente, fica um tanto incômodo. Além do tecido ser grosso, achei que a compressão recomendada não fez muito efeito em termos de comprimir. Deixou a desejar, em minha opinião. Portanto, no quesito conforto, perdeu um pouco em razão do tecido ser muito grosso e áspero. Foi difícil de colocá-la, pois ela tem muitos furinhos, que vão travando dos dedos. E, no quesito eficácia, também não logrou muito êxito. Voltaria a experimentar a marca Sigvaris, mas talvez adquirindo uma compressão menor do que a recomendada.

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.
