Frequently Asked Questions

What are Second Skin Anti-Embolism knee highs?

Second Skin Anti-Embolism is our competitively priced compression range. This style is a unisex knee high knit in a soft smooth knit built for continuous wear during recovery, finished with a soft, non-constricting stay-up top, delivering 18 mmHg anti-embolism graduated compression. Browse the full Second Skin range.

What does 18 mmHg mean, and what does it help with?

The numbers are the pressure at the ankle in millimetres of mercury, decreasing along the limb. 18 mmHg is the anti-embolism class, indicated for reducing thromboembolic risk, recovery at home while reclining or bed-confined, post-surgical recovery at home, periods of reduced mobility. Our compression therapy guide explains each level.

Do these come in plus or wide-calf sizes?

Yes. This style runs from Small to 4X-Large. Plus sizes are graded on calf circumference rather than clothing size, so measure your ankle and calf first thing in the morning before swelling builds and match those numbers to the chart on this page. Our measuring guide walks through each measurement.

How do I put these on and take them off?

Turn the garment inside out to the heel, work the foot in first, then roll it up the limb in stages rather than pulling from the top, which stretches the band. Rubber gloves or a donning aid make it easier. Full instructions are in our guide to putting on compression stockings.

How do I care for them?

Wash after each wear in cool or lukewarm water with a gentle solution — never fabric softener or bleach — and air dry away from direct heat. Most people rotate two pairs so a clean, dry pair is always ready. Full instructions and washing solutions are in our care guide.
