Find Your Perfect Fit
Choosing the right size is the key to getting the best support, comfort, and compression from your New30 Compression Sleeve.
To find your ideal size, simply measure the widest part of your thigh and compare your measurement with the size guide below.
If you're between sizes, we generally recommend choosing the larger size for a more comfortable fit.

Can I wear a single sleeve on either knee?
Yes. Each sleeve is designed to fit either leg - there's no left or right orientation, so you can wear it on whichever knee needs support.
How is this different from your Wide Calf Compression Socks?
This is a low-cut running sock built for training and race day, sitting right at the ankle so it stays hidden under low running shoes. Our Wide Calf Compression Socks go higher, covering the full calf for all-day wear, travel, or long shifts on your feet. Choose this one for running, that one for everyday and travel support.
Do I need this if I already have compression socks?
If your compression socks stop at the knee, they're not doing anything for your thigh and if your discomfort is centered around the knee joint itself, socks alone usually won't address that. New30 is designed to cover both areas in one piece, so most customers use it instead of layering a sock and a separate knee sleeve.
Is it hard to put on?
No. There are no zippers, clasps, or laces. Just pull it on like a regular sock and smooth it into place. Most customers say it takes just a few seconds once they get used to the fit.
Can I wear it during the day too?
Yes. The sleeve is thin enough to wear under work pants or leggings for all-day use, and many customers wear it during work shifts, workouts, or daily activity — not just for sleep or rest. If you're using it for overnight wear specifically, we recommend the standard (non-Pro) fit for a lighter feel.
How do I know which size to pick?
Sizing is based on your regular shoe size, not a leg or calf measurement. Choose Man (EU 39–44) or Women (EU 34–39) to match the shoe size you normally wear. If you're right between the two ranges, size up for a more comfortable fit.
Can I order a pack in different sizes?
Yes. If you're ordering more than one pair, you can select Man or Women sizing for each pair individually at checkout, useful if you're buying for two people, or if your foot size sits right between the two ranges. If you need help choosing, contact us before ordering.
How do you wash these?
Hand wash in cold water and lay flat to dry. Avoid the dryer and avoid chlorine bleach, as heat and harsh chemicals can break down the compression fabric and elastic over time. Proper care will help the sleeve keep its compression strength wash after wash.
What if it doesn't work for me?
We stand behind the product. If New30 isn't providing the support or relief you expected, contact us within 30 days and we'll help make it right, whether that's a different size, a different fit, or a refund per our return policy.
