"This brace actually STAYS UP and fits my weird shaped legs due to lipedema. The support has reduced pain and allowed me to move around better because the side bracing flexes amazingly well. All my doctors write down the name so they can help other patients with the same issues. THANK YOU FOR MAKING THIS PRODUCT!!! Just ordered 2 more!"

Details

All legs are not the same shape — and most knee braces aren't built for yours. Big Bones is purpose-built for plus-size legs with a flared, wider top and built-in side springs and support stays that run to the upper edge. No rolling, no readjusting, no compromise.

Same medical-grade knitted compression and silicone gel padding as our original sleeve, redesigned with a wider V-shape that fits thighs of size without cutting in or sliding down. We prototyped this one until it was perfect.

Built for daily wear, work, recovery, and roller derby. A real knee brace for Lipedema sufferers and anyone who's been let down by "one-size-fits-all" gear. HSA/FSA eligible.

Great brace!!

I don’t skate, but I do work on my feet all day. Got the brace as I did something to my knee, and it’s treated me very well so far. Some slight slippage, but nothing super serious. Reduces my pain and keeps my knee from popping and moving out of place most of the time! There is a stark difference...

Hallelujah, it fits.

Believe the hype; if other knee braces are making you feel furious and fat, buy this and be happy. It's the first knee brace that actually stays on my leg. It fits well -- tight enough but not TOO tight -- and provides the support I'm looking for. I'm so happy to have found this. THANK YOU to Old...

LOVE this brace so much I bought a second one

LOVE this brace so much I bought a second one immediately😂 I’m a stretchy jointed human, and these really help on bad knee days. I’ve gotten a ton of compliments already with one pink brace, and one purple one 💜💕

For someone whose knees sound like bubble wrap on

For someone whose knees sound like bubble wrap on a regular basis, the old one knee brace is the only thing keeping me upright while learning to derby skate. Praise old bones.

This knee brace has changed my life

This knee brace has changed my life. I know that sounds crazy, but I fell down some stairs a year ago and have a torn meniscus. Doc recommends full knee replacement but I need to lose weight first. Hard to lose weight with lipedema, then the added knee injury. Then I found this knee brace that ac...

Works

I got the Big Bones knee sleeves. They actually fit my 26" thighs and guess what? They work! I work in a high school at night and can walk from 9,000 to 15,000 steps a night. They keep compression on my knee and are a real help in getting through my work night. Only thing wrong is after a few day...

Common Questions

How is this different from your regular knee sleeve?

The Big Bones Knee Brace is purpose-built for plus-size legs with an extended size range up to 4XL. The construction is specifically engineered for larger circumferences — it won't roll down, bunch up, or lose compression like regular sleeves that are simply stretched to fit.

Will it stay up on my legs?

Yes. This is our customers' #1 concern and our #1 strength. The Big Bones brace is engineered to stay in place on larger legs. Customers with lipedema, cone-shaped legs, and larger thighs consistently report it stays up all day — even under jeans.

What sizes are available?

Big Bones is available in sizes that extend well beyond standard knee sleeves, up to 4XL. Measure the circumference of your leg 4 inches above the kneecap and match to our sizing chart.

Does it fit under jeans?

Yes. Multiple customers specifically mention wearing it comfortably under jeans all day. One customer even removes the gel padding for an even slimmer fit under denim.

Is this HSA/FSA eligible?

Yes. The Big Bones Knee Brace is HSA/FSA eligible through TrueMed.
