Why JOBST ACTIVA Opaque Knee-High Compression Socks?
The JOBST ACTIVA Opaque line is built for people who want support that does not look medical. The knee-high closed-toe style combines a soft, opaque knit with 15-20 mmHg graduated compression. The result is a sock that helps improve circulation, reduces mild leg fatigue, and blends into everyday wardrobes.
- Graduated compression engineering: The 15-20 mmHg level applies the greatest support at the ankle and decreases toward the knee, encouraging upward blood flow and helping reduce pooling in the lower legs.
- Soft, opaque appearance: The knit fabric provides coverage similar to regular dress or trouser socks, so the sock blends into your outfit without looking clinical.
- Closed-toe comfort: Full-toe coverage protects the foot and works well with closed shoes, boots, and sneakers.
- Durable daily wear: The ACTIVA Opaque line is made to hold its shape and compression level through repeated wearing and washing.
- Knee-high coverage: Extends to just below the knee, supporting the calf and lower leg where fatigue often builds.
- Multiple color and size options: Available in Black, Sun Bronze, and Silky Beige, with sizes Small through X-Large.

Who Is It For?
This sock is designed for adults who want moderate daily support without the feel of a medical garment. It may be especially helpful for:
- People who stand or walk for most of the workday
- Professionals who sit at a desk for long stretches
- Travelers taking flights or road trips
- Anyone experiencing mild leg fatigue or swelling by day's end
- Those looking for discreet, opaque compression that pairs with work or casual clothing

How to Use, Wear, and Apply
- Put the sock on in the morning when leg swelling is lowest.
- Gather the sock from the toe up, turning the fabric inside out until you reach the heel pocket.
- Slip your foot in and make sure the heel pocket lines up with your heel.
- Gradually pull the fabric up your leg, smoothing wrinkles as you go, until the top band sits just below the knee.
- Check the fit: the top band should stay in place without rolling or digging, and the toe area should feel comfortable.
- Remove at bedtime or immediately if you feel numbness, tingling, or discomfort.

Size Chart and Fit Guide
Finding the right size helps the sock deliver the intended compression and stay comfortable throughout the day. For this knee-high style, measure the circumference of your ankle (cB) and the widest part of your calf (cC).
How to measure:
- Measure your ankle circumference at the narrowest point above the ankle bone.
- Measure your calf circumference at the widest part of the calf.
- Compare both measurements to the chart below and choose the size that fits both points.
| Size | Ankle Circumference (cB) | Calf Circumference (cC) |
|---|---|---|
| Small | 7"-8" (18-20 cm) | 10 1/2"-14 1/2" (27-37 cm) |
| Medium | 8"-9 1/2" (20-24 cm) | 11 1/2"-15 1/2" (29-39 cm) |
| Large | 9 1/2"-11" (24-28 cm) | 12 1/2"-17" (32-43 cm) |
| X-Large | 11"-12 1/2" (28-32 cm) | 13 1/2"-18 1/2" (34-48 cm) |
Fit tip: If your ankle and calf measurements fall into different sizes, choose the larger size for comfort. For lower compression styles, shoe size alone may be enough to determine fit, but leg measurements are the most reliable guide.

Frequently Asked Questions
What does 15-20 mmHg compression feel like?
15-20 mmHg feels like a firm, supportive hug around the ankle and calf. It should feel snug but not painful. If you experience numbness, tingling, or discomfort, remove the sock and consult a healthcare provider.
Can I wear these socks all day?
Yes. The JOBST ACTIVA Opaque 15-20 mmHg socks are designed for all-day wear during work, travel, or daily activities. Many people put them on in the morning and remove them at bedtime.
What is the difference between closed toe and open toe?
Closed-toe socks cover the entire foot, including the toes. They are a good match for closed shoes and provide full foot coverage. Open-toe socks leave the toes exposed and may be preferred by people who want more toe freedom or who wear sandals.
How do I know which size to order?
Measure your ankle and calf circumferences and compare them to the size chart. If you are between sizes, choose the larger size. For lower compression styles, shoe size alone may be enough, but leg measurements are the most reliable guide.
Can compression socks help with varicose veins?
Compression socks may help manage symptoms associated with varicose veins, such as aching, heaviness, or mild swelling. They do not cure or eliminate varicose veins. Talk to a healthcare provider for a diagnosis and treatment plan.
Are these socks safe for people with diabetes?
If you have diabetes, peripheral arterial disease, severe skin conditions, or any condition affecting circulation, consult your healthcare provider before wearing compression socks. They can help you choose the right compression level and fit.
How often should I replace these socks?
With daily wear, most compression socks should be replaced every 3-6 months. Signs that it is time for a new pair include stretched fabric, reduced compression feel, or a loose fit around the calf or ankle.
