Before you decide

Questions we get asked most.

Firm and supportive, never tight or painful. The patella opening should sit around your kneecap, not on top of it, and the hinges should line up with the sides of the joint. If it leaves deep marks, makes your lower leg tingle, or your foot feels cold, loosen the straps or size up.

You'll feel them, but they shouldn't dig in. The hinges sit in padded channels on each side of the knee and bend with you rather than against you — that's what stops the brace from sliding or twisting when you move. Most people stop noticing them within a day or two.

A sleeve gives warmth and light compression and nothing else. This has dual side hinges and adjustable buckle straps, so it actually limits sideways movement and holds position under load. If a sleeve has stopped being enough, this is the next step up.

Measure the circumference of your leg about 15 cm (6 in) above the centre of your kneecap, standing with your leg relaxed and straight. Match that to the size chart on this page. Don't go by trouser size, and if you fall between two sizes, take the larger one.

Yes. The design is symmetrical, so one brace fits either leg. If you want support on both knees at once, the 2-pack is the cheaper way to do it.

It's built for movement — gym sessions, hiking, court sports, long days on your feet. Strap it a little tighter for high-impact activity and loosen it afterwards. For a diagnosed injury or post-surgery recovery, check with your physio or doctor about what support is appropriate first.

Under loose or straight-leg trousers, yes. Under slim-fit trousers or jeans it will show, since the hinges add bulk at the sides. Most people wear it over leggings or under tracksuit bottoms.

Close the velcro straps first so they don't catch, then hand wash in cool water with mild soap and air dry flat. No machine, no tumble dryer, no ironing — heat ruins the elastic and the velcro.

Orders are processed within 1–2 business days and usually arrive in 7–12 business days. You'll get a tracking link by email as soon as it ships.

30 days

Try it for a full month.

You won't know if this is the right support for your knee until you've worn it through a normal week — a few walks, a few stairs, a session or two. So wear it properly. If it isn't right, send it back.

Absolute lifesaver for long shifts

I'm a registered nurse and easily log 15,000 steps a day. My left knee used to throb by lunchtime, but wearing this completely eliminates the midday ache.

M
Matthew Harding

I stand on roofs all day and my knees usually take a beating. This brace gives me the exact support I need without cutting off circulation. Highly recommend for tradesmen.

J
Joanne Fuller
Fantastic for recovery

Bought this two months after my ACL reconstruction. It gives me the lateral stability I need to feel safe walking on uneven ground again.

S
Sarah Jenkins

It definitely relieves the tension in my right knee when I'm walking downstairs. My only gripe is that it's a bit too thick to wear under my regular straight-leg jeans. Works great over them, though.

C
Calvin Rhodes
Solid piece of gear

I use it for bowling. The slide approach puts a lot of torque on my knee, and this sleeve handles the stress perfectly.

D
Derek Holloway
Perfect for mechanics

Working under cars requires constantly getting up and down. This brace feels like a spring, helping me stand back up with much less effort.

R
Roy Lyle

A brace that actually works , I like the side braces, helps stabilize the knee, the only thing I would like to see is more velcro on the criss cross straps so they could have more adjustment. Not going to make your knee better but helps, unlike the shoelace dial braces offered out there.

The HF knee Brace helps alot with support and not twisting me knee joint. It fits well
I recommend this knee brace for active people

T
Tim

Took way more time than would be considered reasonable shipping time. Product seems of poor quality just taking out of packaging.

P
Philip Torres
Good, but leaves strap marks

The support is phenomenal for my arthritis. My only complaint is that if I wear it directly on my skin, the straps leave temporary indentations. Best worn over leggings.

A
Arthur Blake
Scratches my leg terribly

The edges of the velcro are incredibly sharp and dig right into my calf when I bend my knee. Very uncomfortable and poorly finished.

E
Eugene Lawson
Makes driving bearable

Long road trips used to cause shooting pains in my driving leg. Slipping this on before a long haul keeps the joint compressed and completely pain-free.

D
David Ross

The brace felt great for the first three days, but the velcro straps stopped sticking completely by the end of the week. For the price, I expected much better durability.

W
Wendy Carmichael
Surprised by the posture benefits

Because my knee feels secure, I am no longer favoring my other leg. My hips are aligned again and my lower back feels miles better.

E
Emily Chen-Smith

I’ve struggled with osteoarthritis for years. I slipped this on yesterday for my evening walk and felt an immediate difference. It keeps my knee stabilized perfectly.

M
Marcus Vance

Great product. Easy to put on and take off.

M
Monica Yates
A bit bulky for running

It provides excellent support, but it's a little too heavy for my daily jogs. I've relegated it to weightlifting days instead.

S
Simon Garrett
Eases my muscle tension

My thigh muscles used to cramp up from overcompensating for my weak knee. Since I started wearing this, my whole leg feels relaxed.

J
Jessica Bradley

I bought this for a meniscus issue, but I've noticed that because I'm not limping or favoring that leg anymore, my lower back pain has also disappeared. Amazing side effect!

B
Brian O'Connor

Most knee sleeves slide down my leg after ten minutes of running. The straps on this one keep it locked exactly where it needs to be.

V

Finally back on the tennis court

I thought I had to hang up my racket for good. This gives me the confidence to pivot and serve without fear of my knee giving out.

A
Amanda Lewis

The sizing chart is a little off. I measured my thigh as instructed and got a Large, but it feels a bit too tight behind the knee. It does offer good support, though.

A
Alison Vance
Great quality, tight fit

The neoprene is thick and seems very durable. It is quite snug around the thigh though, so measure carefully before ordering.

T
Tyler Wood

I use this on heavy squat days. The side stabilizers give me so much confidence coming out of the hole.

L
Leonard Bishop
Keeps my knee warm

The cold winter air usually makes my joints stiffen up. Wearing this acts as a great insulator while providing structural support.

E
Evelyn Cross
Simply amazing

Easiest brace to put on. The design is intuitive and it stays put all day.

N
Nancy Henderson

Five stars all the way. It compresses the joint just right and alleviates the sharp pains I usually get when bending down.

J
James Long
Great brace for the price

Great brace really helps with my knee pain

R
Robert Franklin

I've bought $80 braces from the local drug store that didn't work half as well as this one. It's breathable and the stitching looks very durable.

H
Harold Quinn
Highly recommended for seniors

At 82, my balance isn't what it used to be. This brace adds a layer of steadiness that prevents me from stumbling.

C
Christine Gallagher

I don't know if my legs are just the wrong shape for this, but no matter how tight I pull the straps, it ends up around my shin after a short walk. Very frustrating.
