Sigvaris 500 Series
Model 504C

Sigvaris 503-C Knee High 30-40 Open Toe 

High Compression Unisex Stockings 
Natural Rubber Material

• Remarkable
Numerous scientific studies have shown the medical effectiveness of the 500 Natural Rubber Series. The material has a remarkably low 1% to 2% fatigue rate, making the stocking ideal for those with serious indications or long-term therapy.

• Unique
Manufactured from double-covered elastodien yarn, a yarn made from soft, natural rubber and offering the greatest degree of elasticity while maintaining sustained compression throughout the day.

• Easy Wear
Made from a porous, extremely permeable, and highly elastic fabric which makes the stocking easy to pull on and off, even in the higher compression categories.

• Durable
The knitted fabric is double-covered textured yarn, and therefore retains its shape and is extremely durable.

Discount's customer service was great. But the Sigvaris I always get, 504C Knee-Hi, are problematic. I start the day with them on properly and they're great for a little while. But then the open toe (I can't wear closed toe) works back towards the center of my arch and the compression around that area gives me foot cramps. So I have to remove my shoes and work the ends back towards my toes. If they're too much onto my toes, that hurts my toes. They're sized right according to the Sigvaris measurement guide, but for about $100/pair I'd like them to work better.

I have worn these for 33 years and they are my favorite stocking. I have tried others and keep coming back to these. However, I have found in the last few years that they don't last as long as they use too. I've noticed snags and I had two pair that ran. That has never happened before. I guess I should have sent them back, but I had already worn them for some time. It's just I usually can have a pair last 6 mos easily if not longer.

I need the compression due to chronic edema, so I wear the socks on both legs all day. I use the knee-highs because the thigh highs wouldn't stay up. I like the compression of the Sigvaris, but they don't fit right. The stretch band near my toes (open toe compression socks) keeps sliding back towards the arch of my foot, at which time it causes a cramp in my foot. So I have to take my shoes off and yank on the socks to get the ends closer to my toes again -- quite a nuisance, especially if I'm in a public place or driving. I've tried a couple of other brands with lousy results. At the outrageous price of these socks, I can't just keep trying different ones. So, I suffer with the Sigvaris, which at least work well otherwise. Does anyone know why they cost so darn much?

I have worn compression knee highs for 30 years. Of course over that period of time I have worn several different brands. Sigvaris tops tham all. I highly recommend this brand.

have been buying stockings from you for quite a few years. Have been very happy with the results. I have had swelling most of my life in my right leg. Before using your stocking,I had trouble walking normally because it swell up and ache. But now i can actually see my leg shrink to where it all most the same size as my other leg. Will continue buying stockings from you, the material is very durable and lasts a long time until it is time to buy a new one. Usually every six months or so.

Q & A

Ask a Question
1 question for this item
Q: Is the Sigvaris 504C available with a closed toe, rather than an open toe ??
A: No that model only comes in open toe.
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.
